Setting Up Email When Using a Commercial ISP
 

Question 1.1 I use a commercial ISP when dialing in from home. Is that OK?

  • It surely is; if the UIC phone exchanges are not in your local untimed calling area, the phone charges for using the UIC dialin lines can be very steep. And both DSL and cable connections -- which the ACCC does not offer -- are very much faster than the UIC dialins, making them a very attractive alternative if they're available to you.
  • Generally, you can still use your uic.edu return address: Usually you can still use Eudora (or another personal computer email program) with your UIC.EDU email address when using a commercial ISP. Whether you can or not, however, is up to your ISP.
  • What SMTP (outgoing email) server to use: You must, however, either use the ACCC's authenticated SMTP (outgoing email) server or your ISP's SMTP server when sending your email. You can't just use the ACCC's regular, un-authenticated SMTP server (which is smtpserv.cc.uic.edu).
    For an explanation of the problem and detailed information on how to set up all common email programs, and a list of the SMTP servers for many common local and national ISPs, see Changing to Your ISP's SMTP Server.
  • If your commercial ISP is AOL:
    • When the ACCC first changed its policy to restrict its SMTP servers to use by local UIC machines, AOL didn't provide SMTP service, so people using AOL had to either use the AOL email program or WebMail when they dialed in via AOL.
    • As of AOL version 6.0, AOL seems to have solved this problem in a particularly ingenious way. It doesn't matter what SMTP server you have your email program set to use; while you're dialed in using AOL, all SMTP requests are answered by AOL's own SMTP server.
    • So people using AOL 6.0 are no longer "out of luck", they're actually pretty lucky. They can set Eudora (or whatever other email program they use) up to use one of the UIC SMTP servers, such as smtpserv.cc.uic.edu, which will work while they're on campus or using an ACCC dialin line, and not change anything when they're dialing in using AOL.
    • We don't at this time know whether this works in earlier versions of AOL.

 
     
General Questions Concerning Email at UIC
 

Question 2.1 What's the difference between a netid, an account, and an email address?

  • A netid is a string of 3-8 characters by which you are known. It usually represents the name of the person and has no periods or other punctuation. For example, 'adabyron' is a netid. More details on netids.
  • An account gives you the ability to login to, or otherwise use, a specific computer. You normally have a login id and password associated with an account. When you get an account on an ACCC machine, we always use your netid as the login id. This way, you only need remember one login id no matter how many machines you use.
  • Normally, each account has an associated mailbox and mail address. This would be of the form loginid@machine. For example, if Ada Byron had an account on tigger, she could use adabyron@tigger.uic.edu for a mail address. Note that adabyron is both the netid and the login id.
  • Wouldn't it be nice to have a single, stable email address? Even if you moved your mailbox or accounts, the old address would send mail to your new account. Well, you have one. Ada Byron can use adabryon@uic.edu. This is a special mail alias; it doesn't refer to a specific machine, but can be used to send mail wherever you want on the internet.
Thingy What it is and comments
adabyron netid, which will be used for a login id for all of your ACCC accounts
adabyron@uic.edu email address that is an "alias"; email sent to this address is automatically forwarded to other accounts. (But you have to tell it where you want it forwarded to.)
adabyron@icarus.uic.edu email address for an email account on icarus; adabyron@icarus.cc.uic.edu is also OK
adabryon@mailserv.uic.edu email address for an email account on mailserv; adabyron@mailserv.cc.uic.edu is also OK
adabyron@tigger.uic.edu email address for an email account on tigger; adabyron@tigger.cc.uic.edu is also OK

Question 2.2 What about these other email addresses? Are they valid?

The email addresses listed in What's the difference between a netid, an account, and an email address? above are the only valid email address for ACCC email accounts. There are other email addresses that might work, but you shouldn't use because they're either obsolete or subject to breaking.

These bad email addresses include:

BAD Email Address Why it's bad.
Ada.Byron.Lovelace@any.machine.uic.edu Obsolete UIC mail-name
U12345@uicvm.uic.edu This a CMS email address, which is bad because UICVM/CMS no longer exists.
adabyron@any.other.machine.uic.edu The proper machine names for ACCC email accounts are: uic.edu, icarus.uic.edu (or icarus.cc.uic.edu), mailserv.uic.edu (or mailserv.cc.uic.edu), or tigger.uic.edu (or tigger.cc.uic.edu).

Some people have discovered that they will receive email that's addressed to their netid with a machine address other than uic.edu, icarus.uic.edu (or icarus.cc.uic.edu), mailserv.uic.edu (or mailserv.cc.uic.edu), or tigger.uic.edu (or tigger.cc.uic.edu).

Even if you're sure that an email address with another machine address works for you now, don't use it -- it might not work tomorrow. In most cases, these addresses work because the machine that your email account is on answers to one or more alternate Internet domain names. The Internet domain names that machines answer to will change as their functions change. The addresses given in the table in What's the difference between a netid, an account, and an email address? will always work. No other addresses come with that guarantee.


Question 2.3 I would like to use netid@uic.edu as my email address; how do I do that?

  • The only thing you have to do is tell our utility what real email address you want your your-netid@uic.edu email sent to. Do this by filling out the form on our Email Forwarding Web Page. Changes take place immediately. Any email address will do; it doesn't have to be an ACCC server or even be on campus.

Question 2.4 I'm having trouble sending email to off-campus locations.

  • If you're off-campus yourself and using a commercial ISP (not WebMail or the ACCC's dialin lines) then most likely the problem is you're trying to use the ACCC's regular, unauthenticated outgoing SMTP servers to send email. When using a commercial ISP, you have to set your email program up to use your ISP's SMTP (outgoing email) server or use the ACCC's authenticated SMTP server.
  • See I use a commercial ISP when dialing in from home. Is that OK? .

Question 2.5 I deleted an email message that I shouldn't have. Is there any way to get it back?

  • Most email programs have options that allow you to undelete email messages that you have just deleted; see the documentation for your email program for instructions.
  • If the message in question was in your ACCC UNIX Inbox or another IMAP email folder -- an email folder that's stored on the ACCC email server rather than on your personal computer -- and has been there at least overnight, it might be in the backup copy of of that email mailbox on the server.
  • If:
    • Your email Inbox is on tigger or icarus, and
    • The email was in a mailbox on tigger or icarus overnight,
    It's possible that you can use dsmc to restore files. See I deleted an email message that I shouldn't have. Is there any way to get it back? in the DSMC FAQ.
  • If your email Inbox is on mailserv, and the message had been in a mailbox on mailserv overnight, send an email message explaining exactly what message you want back and where it was (in your Inbox or another IMAP folder on mailserv) to systems@uic.edu; we might be able to get it back for you.
  • If, however, you downloaded the message to your personal computer without its having been on tigger, icarus, or mailserv overnight, there isn't anything we can do to help you get it back. Another important reason to run backups on your personal computers on a regular basis.
  • Please note: We only keep the overnight backups for a short time. If you find an important message -- one that we can get back for you! -- is missing, begin working on getting it back right away!

Question 2.6 My email account is expiring. How do I transfer my email and addressbook over to my new account?

  • If you are leaving UIC:
    • Your account will expire one semester after leaving for students and 90 days after leaving for staff members.
    • You can use a local Internet Service Provider (ISP) for email and Internet connection. See Finding an ISP.

Question 2.7 Can I have my email account automatically reply to incoming mail while I'm on vacation?

  • Yes; use our Email Filters Web Page; It includes a utility that will automatically respond to any email sent to your account.
  • Don't use the auto-respond feature that comes with your email program. At best, you will respond to email that you shouldn't respond to, such as spam and email lists, and at worst you won't respond to anything until you get back.
  • The ACCC vacation response filter has been carefully set up to only respond to "real" messages, and runs all the time, regardless of whether your email program is logged in.

Question 2.8 Can I have other automatic actions taken in response to new incoming email messages?

  • Email filters automatically take action on each new incoming email message. They can do almost anything you'd do by yourself, even send a canned reply.
  • To sort out spam, the ACCC applies the ACCC AntiSpam Filters to all email the comes in addressed to any address at uic.edu, including netid@uic.edu email that is not delivered on-campus.
  • The email that is definitely spam is thrown away; the email that may be spam is delivered to your spam mailbox on the server.

Question 2.9 What can I do about spam email?

  • The ACCC applies the ACCC AntiSpam Filters to all email the comes in addressed to any address at uic.edu, including netid@uic.edu email that is not delivered on-campus.
  • The email that is definitely spam is thrown away; the email that may be spam is delivered to your spam mailbox on the server.
  • The ACCC's antispam email filters can help; the Email Filters tool has a separate section that allows you to change the set up your antispam filters.
  • See Canned Spam Filters for more information and instructions on how to set them up.

Question 2.10 Can I use more than one email program to read my email?

  • Yes, you can, so long as you only use one at a time. (For example, you can use WebMail at home and Eudora at work, but make sure that you close Eudora before you leave work.)
  • There is only one caveat: if you're going to be using several email programs, it's best that they're all set up to use the same email protocol. That is, either they all use IMAP or they all use POP. Two of the three ACCC-supported email programs -- WebMail and pine -- use IMAP, so if you're going to use Eudora or another personal computer email program with either WebMail or pine, you should have it set up to use IMAP rather than POP. (POP generally is the default for personal computer email programs.)
  • This used to be a "has to do" requirement -- mix up POP and IMAP and eventually you'd mess up your Inbox. Now that is no longer true. The ACCC has upgraded it's POP servers on mailserv, icarus, and tigger, so they are now compatible with the IMAP servers on these machines. So it is no longer required that you not mix POP and IMAP.
  • But it is still to your advantage not to mix them. If you only use IMAP, you will be able to read all the email that you leave online from any of your email programs, for example.
  • Eudora Email for Macs and Windows has detailed instructions on how to convert Eudora to use IMAP. While the specific instructions in these pages document won't be useful if you want to convert Netscape or Outlook to use IMAP, they do have all the information that you'll need to set them up to use IMAP.

Question 2.11 I want to use another email program; not Eudora, pine, or WebMail. Is that OK? Will you help me?

  • Yes, that's OK, so long as you only use one at a time (see above). But we probably won't be able to help you much.
  • Do you want to use IMAP? We can help you with that. Eudora Email for Macs and Windows has detailed instructions on how to convert Eudora to use IMAP. While the specific instructions in these pages document won't be useful if you want to convert Netscape or Outlook or any other email program to use IMAP, they do have all the information that you'll need to set them up to use IMAP.

Question 2.12 I'm having trouble; my email program won't let me delete an email message or won't let me download my email or ....


 
     
Email Quotas and Limits
 

Question 3.1 I received a message warning me about email quotas; what do I do?

  • To keep the ACCC email machines running smoothly (and to conserve on our limited disk space), we have limits -- quotas -- on the total size of the mail files can be in each person's account on them.
  • What happens if you "go over quota"? You will receive warning messages as you approach your email quota:
    • If your email account is on icarus or tigger, you will receive the warning messages as the size of your Inbox approaches and exceeds your Inbox soft quota and as it approaches and reaches your Inbox hard quota.
    • If your email account is on mailserv, you will receive the warning messages as the total size of your Inbox, your IMAP mailboxes, and all the other files you have on mailserv approaches and exceeds your mailserv soft quota and as it approaches and reaches your mailserv hard quota.
  • You must take these warning messages seriously; the consequence for staying over your soft quota for 7 days or for reaching your hard quota is that new incoming email messages addressed to your account will be "bounced" -- returned to their sender with an error message that says that your account is over quota.
  • You will not begin to receive new incoming email until you go back down below your soft quota. Resumption of the delivery of new incoming email is automatic, however, and occurs as soon as you go below your soft quota.

  • What you need to do to fix an email quota problem depends on which email server your account is on, which email program you use, and how you use it.
  • We have groups of Web pages with instructions for fixing email quota problems with each of the email programs that the ACCC supports (Eudora on your PC or Mac, pine on icarus or tigger, and the Web-based WebMail) for each server; see the Email Diagnostics and Quota page for links to these pages.

  • The Email Diagnostics and Quota pages also explain how to use the ACCC Email Quota Tool. After you enter your ACCC netid and password and select the server your email account is on, if necessary, the ACCC Email Quota, Download, and Delete Tool will display your email and disk quotas and offer links to pages that list your largest email messages and, for icarus and tigger, that allow you to download or delete your largest files.

Question 3.2 How can I tell how much email I have on my icarus/mailserv/tigger account?

  • Go to the ACCC home page (or any other ACCC Web page) and click the purple Email button at the top of the page.
  • Click the Email - Quota Tool link.
  • After you enter your ACCC netid and password, the ACCC Email Quota, Download, and Delete Tool will display your email and disk quotas and offer links to pages that list your largest email messages and that allow you to download or delete your Inbox or other email mailboxes.
  • The Quota tool is the only way to check your email quota on mailserv.
  • Or, if you're logged into icarus or tigger, you can use the quota command:
    on icarus:
    quota -v
    on tigger:
    quota
    The second line of the output from this command gives your Inbox quotas and the current size of your Inbox. For example, the /var/mail info from icarus:
    Filesystem     usage  quota  limit    timeleft  files  quota  limit    timeleft
    /homes/home2    1030  10240  15360                247      0      0
    /var/mail        832  12288  38664                  2      0      0
    
    The first number is the space taken up by your Inbox, the second is your Inbox soft quota, and the third is your Inbox hard quota, all in units of KB.

Question 3.3 How long are my email messages kept?

  • The short answer is forever -- or at least until you delete them.
  • But assuming that we're talking about email that you leave on icarus, tigger, or mailserv, that's not the complete story. You have a finite amount of storage space for email on your account. Keeping too much email on the server can cause problems, including having your new incoming email not delivered to you. (Instead, it would be sent back to whomever sent it to you with a message saying your account is over quota.) So sooner or later you will need to either delete messages or move them off the server.
  • For brief information, see The Email Space Limits for ACCC Servers.
  • For more complete information, see the links in I received a message warning me about email quotas; what do I do? above.

Question 3.4 Is there any limit on size of email messages you send or receive with WebMail? Pine? Eudora? Anything else?

  • The limit for outbound mail is 40 Mb. However, if we're talking attachments, with MIME-encoding, that translates into about a 25 Mb file. This limit is in the SMTP server, and applies equally to users of any email program, including pine, Eudora, and WebMail.
  • The size limit for inbound email -- email that comes in UIC addressed to any ACCC email server -- is currently 10 Mb. (We plan raise the inbound limit to 40 Mb also sometime in the near future.)

 
     
Mail Forwarding
 

Question 4.1 Forwarding Email: How do I forward my email to another account?

  • To determine where mail sent to netid@uic.edu will go, fill out the form on our Email Forwarding Web Page. Changes take place immediately. You can use any valid email address, on-campus or off.
  • If you want email delivered to icarus, tigger, or mailserv forwarded somewhere else, you can use a custom Email Filters filter to do it.

Question 4.2 But what if mail actually gets sent directly to my account? How do I forward that mail?

  • You can use the Set up Email Filters function of the Email Filters Web page, but if your email account is on icarus or tigger, you might find the direct route, below, easier.

  • The direct route, if your email account is on icarus or tigger. (It won't work for mailserv accounts because you can't login to mailserv.)
    • To forward mail that was sent directly to a UNIX (e.g. tigger,icarus) account (e.g., netid@tigger.cc.uic.edu) you need to have a file in your home directory called .forward (yes, it does start with a period). In the file is the address to which you want mail forwarded. This can be accomplished with one simple command. For example, Joe Smith decides he wants his icarus mail forwarded to his tigger account; on icarus, he could need to enter:
      echo fred@aol.com > .forward
    • If you would like to forward to multiple addresses, then you can add additional addresses like this:
      echo joe@aol.com >> .forward
    • If you would like to keep a copy as well, then simply add yourself as another recipient:
      echo your-netid@tigger.uic.edu >> .forward
      That will create the file and put the address within it. Replace the above address with your own address to forward your mail. NOTE: Remember to set forwarding to a real machine and not back to your netid, i.e., not to adabyron@uic.edu, but rather to jpublic12@icarus.uic.edu or adabyron@tigger.uic.edu.

      To stop mail forwarding, you just need to remove the .forward file. You can do that by typing:

       rm .forward

Question 4.3 How do I stop or change mail forwarding?

  • To stop mail forwarding in icarus or tigger, you just need to remove the .forward file. You can do that by typing:
    rm .forward
  • To change the address the email is forwarded to, type
    echo netid@node.node > .forward
    This will overwrite any existing .forward file.

 
     
Email Problems with Poorly Configured Firewalls
 

Question 5.1 Since I installed the Windows XP SP2 upgrade or Mac OS 10.2+ on my computer or some other firewall, sending an email message now takes 10 to 30 seconds. How do I fix this?

  • The problem is only occurs when you use the ACCC's on-campus only, non-authenticated outgoing SMTP server, smtpserv.cc.uic.edu.
  • When you send an email message using smtpserv.cc.uic.edu, the server attempts to contact your machine via identd. Normally your machine would simply reject the connection and things go quickly. When a firewall is installed, the identd connection is blocked so the SMTP server's attempt to connect has to time out, which is where the delay comes from.
  • You might be tempted to turn the firewall off -- that is not the answer. The real solution is to allow incoming access for port 113 (identd) from our SMTP servers.
  • But only do this if you are using smtpserv.cc.uic.edu.
  • The ACCC does not use identd on the ACCC's authenticated SMTP server, mail.uic.edu, so if you use this SMTP server, the best thing is to have a firewall and to keep port 113 blocked.

  • Here's how to fix this with Windows XP SP2 firewall. These instructions are specifically for Win XP, but the info can be used with any firewall.
    1. Start -> Control Panels -> Windows Firewall. This opens the Windows Firewall control panel.
    2. Click the Exceptions tab, then click the Add Port... button toward the bottom of the panel.
    3. In the Add a Port dialog box, fill in the following information:
      • Name: ident
      • Port number: 113
      • Click the TCP radio button.
    4. Click OK. ident will be listed in Programs and Services.
    5. Click OK to close the Windows Firewall window.
  • For more information:

    2. And Microsoft Support's Adding a Port Exception: http://support.microsoft.com/default.aspx?kbid=875357#7


  • Here's how to fix this with for the Mac OS 10.2+ firewall. To free port 113, click on:
    1. Blue Apple menu in the upper left corner of your screen
    2. System Preference
    3. Sharing icon
    4. Firewall tab
    5. New
    6. Other from the dropdown menu
    7. For port, enter 113
    8. For description, enter s/indent
    9. Click Ok

 
     
Miscellaneous
 

Question 6.1 My pal sent me a .zip file (or .exe or .cmd or ...) and when I got I can't unzip (or execute or ...) it. The email message says something about Mimedefang. What's that and how do I get my file back?

  • To make it less likely that you will accidentally execute a malicious attachment, the ACCC runs all incoming email through MIMEdefang.
  • MIMEdefang has a list of attachment types that can cause problems (it's in the MIMEdefang FAQ). Each time an email message comes in addressed to an ACCC email mailbox with one of these types of attachments, MIMEdefang adds .txt to the end of the attachment's name.
  • Windows will not automatically execute a .txt file, nor will it run if you accidentally (or on purpose) double-click it.
  • Are you sure this attachment is one that you want to use? The MIMEdefang FAQ has instructions on how to rename it back.
  • Note that Word and Excel files are not "MIMEdefanged." They can carry macro viruses, so it's up to you to be careful about them.

Question 6.2 I have a mailbox that I want to move from icarus/tigger/mailserv to my personal computer. How can I do that? Can I delete an entire mailbox?


Question 6.3 Can I use pine on tigger or icarus to read my mailserv email? How?

  • Yes, you can. And it can be useful when you're over quota, because pine allows you to sort by message size.
  • For instructions, see Fixing Mailserv quota problems with pine.
  • Note that these instructions apply to other email accounts as well.
  • Or the quick way is to use the ACCC's Move to Mailserv utility, and Continue or Skip through all the other steps until you reach the Final Step: Re-configuring your email reader. (optional) and click Reconfigure Pine for that step. Of course, you will have to choose the icarus tool if you want to reconfigure pine on icarus or the tigger tool if you want to reconfigure pine on tigger.

Question 6.4 Can I delete an entire mailbox?

  • Your email program will likely allow you to delete an entire mailbox. For example, in Eudora for Windows, you can right-click on a mailbox name in the Mailbox window and select Delete. If the mailbox has messages in it, Eudora will ask you whether you are sure you want to delete it. Click Remove it, and the entire mailbox will be deleted.
  • Even if your email program doesn't have a way to delete entire mailboxes or won't delete your mailbox, you can use the delete tools on the Email - Quota Tool Web page.
  • For more information, see Downloading or Deleting Entire Mailboxes with the ACCC Email Tools Quota, Download, and Delete Page .

Question 6.5 My email program shows the messages time 6 hours late in its mailbox indexes. How do I fix this?

  • First, this is a not a problem with our servers. The "Date:" header is created by client software. The servers consider it part of message's payload and do not modify it.
  • This is a known in many email programs. A work-around is to get rid of the "Date Received" column and replace it with a "Date Sent" column. This pulls the info from the "Date:" header and provides a more reasonable time value.
  • Here's how to fix it for Outlook. (Fortunately, this problem is fixed in Eudora 6.1 and higher, because there doesn't appear to be any way to change the columns displayed in the mailbox indexes in Eudora.)
    1. click VIEW
    2. click CURRENT VIEW
    3. click FIELDS
    4. click SENT in the left window
    5. click ADD-> (this will add a new column called "SENT")
    6. click RECEIVED in the right window
    7. click <-REMOVE (this will removed the column called "RECEIVED")

Question 6.6 What about those messages that I receive with the subject: DON'T DELETE THIS MESSAGE?

  • As the text of these messages say, they aren't really email messages. You get them whenever you read your email with a program that uses the IMAP email protocol to handle your Inbox and other email folders. IMAP creates these messages, which it uses for internal record keeping.
  • You shouldn't see these messages when you read your email with an email program that is set up to use IMAP. That includes WebMail and pine, which use only IMAP. You can also set up Eudora, Netscape, and Outlook to use IMAP rather than POP.
  • You will see these messages when you use an email program that is set up to use IMAP along with another email program that is set up to use POP. Say, for example, if you use WebMail and Eudora with POP or Eudora with IMAP and Eudora with POP.
  • If you change your personal computer email program to use IMAP (these days, just about all of them can, including, specifically, Eudora, Netscape, and Outlook), then you should never see these messages again.
  • If you don't want to do that, you can ignore them; the messages are annoying, but harmless.
  • Configuring Eudora for Windows for IMAP explains how to set Eudora up for IMAP. (The options are the same when using Netscape, Outlook, and Eudora for the Mac.)

Question 6.7 I've been getting email messages that I try to send returned as not being deliverable. What's up? The address always worked before.

  • The ACCC has switched to a new SMTP server, the server used to send outgoing email, and we're also using the same software to deliver incoming email messages to people's Inboxes on several of the ACCC email machines. The good news is this server -- qmail -- is very much faster than the software that we used previously. The bad news is that it is more particular about the format of the email messages that it handles.
  • One thing that has cased some problems here at UIC is qmail's insistence that there be no leading or trailing blanks in email addresses. (That's written in the email standards, but our previous software let it get by.)
  • For example, mail addressed to: <adabyron@uic.edu> will be delivered,
    but mail addressed to: < adabyron@uic.edu> will now be returned.
  • If mail that you send to an email address that always worked before is now being returned as undeliverable, check the rejected address carefully; this might be the problem.
  • This seems mostly to be a problem with Outlook. If you have any addresses in your Outlook address book with leading spaces, you won't be able to send email to that address until you remove the spaces. (You can't even fix the problem by correctly typing the address in a note; if Outlook finds the address in your addressbook, it will substitute the addressbook's version for the one you typed. Amazing!)
  • If this is your problem, it's easy to take care of. Take the extra spaces out of that address in your address book and all should be well. The ACCC documentation on Eudora, WebMail, and pine all include instructions on how to use their address books.
