It is a simple matter to forward email to another account. In your home directory create a file called .forward which contains the email address of where you would like the mail to be sent. Once you set up your .forward all of your incoming mail will be sent to the new address listed in the .forward file. The .forward file will continue to work for a maximum or two school terms. CS reserves the right to disable .forward files on inactive accounts without warning.
Most Mailing lists create an inordinate amount of mail.
Those students that will have an inactive account and are unable to forward to another mailbox must remove themselves from all mailing lists. If you're forwarding, it is only acceptable to leave yourself on a mailing list if you know that you're coming back after a one term absence. Otherwise, you should remove yourself from the list and add in your new address. Unlike mail, newsgroups are not a problem as they only download files when requested by the users. You are responsible for your own backups.
