Harvard Mathematics Department : Computing: Mail

Here are some visual guides how to configure your email client to read email from your math account. It covers OSX mail, Entourage, Thunderbird (a standalone program from the mozilla suite), Eudora and Evolution. In all cases, the configuration is similar.

In order to ensure that you will be able to send and receive mail whether you are on campus or off campus, configure your client with IMAP with SSL, and SSL or TLS encryption as outlined below (in general, this means using IMAP/SSL for incoming mail, TLS or SSL for sending mail, whichever terminology your client uses). The side benefit of this is that your mail sessions are fully encrypted end-to- end, making your password and your entire account much more secure.

Note that the server now has to be specified as "math.harvard.edu" in all of the places you're asked for it, not as "abel.math.harvard.edu" or "smtp.math.harvard.edu" or any other alternatives.

For all mail programs, you must configure your client to read only the directory ~/mail. Macintosh Mail refers to this setting as the "IMAP Path Prefix"; Thunderbird calls it the "IMAP Server Directory." If you do not complete this step, the mail program will attempt to index your entire home directory every time you read mail. This will slow down the mail server (and, coincidentally) will slow your local machine, sometimes to the point of making it unusable.

The preferred email configuration for the Math Department includes the following general settings. Below we present visual guides for including these settings in some common email programs:

IMAP/Email Reading Server: math.harvard.edu
Type: IMAP
Use: SSL (or TLS) encryption
Port: 993 (some systems will use 143--allow this if system defaults to it)
IMAP Path Prefix: ~/mail
SMTP/Email Sending Server: math.harvard.edu
Use: TLS (or SSL) encryption
Port: 587

With these settings, VPN will no longer be required, or sufficient for sending mail if you are off campus. VPN will not prevent sending mail and may still be required for other programs.
