Mail Clients

The Department of Computer Science operates its own mail server which is mostly independent of the University mail system. Any email address which ends in is handled directly by the CS mail server. Often, this results in faster response.


Our mail server runs a protocol called IMAP, which was developed at the University of Washington. When you read your email using IMAP, your email always resides on the mail server. Your PC-based email software will let you organize your messages, delete messages, and read them, but they never leave the Unix server. The advantage to this is that, no matter where you are, you see a consistent view of your mailbox and mail folders. With POP, a similar email client protocol, you download your mail from the server to your PC, optionally deleting it from the server. The data stored on your PC and stored on the server are not necessarily synchronized, especially if you check your mail from different locations (such as a PC in the office and a PC at home). We do not provide POP service, except in unusual circumstances.

Mail Tools

These mail tools receive the best system staff support because they are the tools that the staff are most familiar with. There are so many possible mail tools that we cannot know them all.
