Secure SMTP Authentication

Overview

While users have always been required to authenticate with a username and password in order to read their e-mail via POP or IMAP, sending e-mail has always been an open service not requiring authentication. Unfortunately, this situation has led to spammers and others Using e-mail servers in order to send their junk e-mail and mass e-mailings through these servers. In order to combat this problem, it was necessary to require users to authenticate when sending e-mail through a mail server. Secure SMTP Authentication is the name of this service that is used in order to authenticate you when you send e-mail through the MTL SMTP server (mtl.mit.edu). All MTL e-mail users will be required to use this service when sending e-mail through the MTL SMTP server.

Relaying Errors

If you are experiencing problems sending e-mail through the MTL SMTP server, then this could be because you are attempting to send the e-mail without first authenticating to the MTL SMTP server. These errors are called relaying errors and can be fixed by configuring your mail client to use Secure SMTP Authentication.
