Authenticated SMTP Service

How do I get setup with a password or certificate that is needed?

We now support 4 authentication methods: plain-text with an SSL tunnel, Cram-MD5, Digest-MD5, and GSSAPI*. The preferred method is plain-text with an SSL tunnel, using your CS username and a Kerberos 5 password.

Consult the table below and find out what type of authentication you need. Also, verify that the version of your client is supported. Then follow the client link to setup instructions.

* GSSAPI Authentication is something that can be used in some mail clients, but requires more effort to set up. If you would like to use GSSAPI, please send mail to staff@cs.umd.edu.

Note: You can set your incoming port to 25 (the default SMTP port), or 587. Port 587 has the same functionality of port 25 but since some providers have started blocking outbound port 25, using 587 will allow you to get around this. Most mail clients have a option to put in a alternate port.
