Mail System Summary

• Mail Hub
  gpo.stanford.edu sends and receives mail for graphics.stanford.edu. It consists of:
  Exim SMTP Transport and Delivery
  IMAP Mail Access Agent
  Spamassassin Spam Analyzer
  Squirrelmail Webmail client
  Access is available both on and off campus via SSL/TLS encryption to authenticate the client's userid/password

  Inbound Mail
  Mail is collected and stored in maildir format in local directories for each user on our mail server. The mailspool is ~/Maildir and all folders reside as directories in this default location. Inbound mail is tested against several blacklists of known spammers and open relays and may be rejected. Inbound mail content is then analyzed by Spamasassin which does not reject mail but labels any spam before delivery.

  To avoid spamassassin processing or use delivery agents such as procmail or maildrop, see forwarding and filtering mail.

  Outbound Mail
  Stanford requires outbound mail to go through smtp.stanford.edu so our mail server forwards mail for all non-campus destinations there. The requirement to use Stanford servers is enforced by blocking outbound SMTP(port 25). This technique is being used by an increasing number of ISPs which means that if you have a mobile machine, you should configure your outbound mail to contact our server on port 587 instead of 25.

  All mail addresses should have fully-qualified domain names or none at all, e.g.:

  descartes@graphics.stanford.edu

  descartes
  but not

  descartes@graphics
  The fully-qualified domain names are advised, especially when using portable machines.
  Therefore, set your return address as @graphics.stanford.edu
