Mail Relaying

SMTP Authentication

Authenticated relaying is supported for people using off-campus computers. There are a couple different ways to authenticate, with the idea being to support as wide a variety of clients as possible. Clients may initiate a TLS protected SMTP session and present a certificate signed by the client CA of They may also use SMTP AUTH, again with a couple of different options for the details. If they are using an unencrypted session then they must use the CRAM-MD5 digest based authenticator. If the session is TLS protected, then they may use either the CRAM-MD5 authenticator or the PLAIN authenticator. The username and password are the same ones used when the user created their CSAIL IMAP account.
