In an effort to cut down on the amount of spam passing through the network, the CSEE Department has implemented an authentication policy on its SMTP server from a non-campus system.

As of June 17, 2005, in order to use the department’s SMTP server from off-campus, there are two choices:

1) use the campus VPN (no changes will be needed to be done)

2) modify your e‑mail client’s configuration as described below

Detailed instructions are provided for Microsoft Outlook, Microsoft Outlook Express, and Mozilla/Netscape/Thunderbird. If any other program is being used, please see the mail client documentation for instructions.

The outgoing SMTP mail relay needs to be configured to support TLS encryption and the username/password authentication that is used for logging in to any CSEE system.
