if you're supporting AUTH, you really should use TLS as well.

If you use CRAM-MD5 for the AUTH method, it's impossible to sniff
the cleartext password.
TLS is a good idea, but getting your users to enable it in their
clients can be a challenge. It's hard enough explaining how to
enable SMTP AUTH!
Here's an idea, how about a Wiki page dedicated to instructions on
setting SMTP AUTH in various email clients? People could contribute
by taking screen shots of their setup, preferably with
'[EMAIL PROTECTED]' or some similar username.
A more ambitious project would be to use PHP and GD with the proper
fonts to automatically fill in the fields and generate a completely
custom "how to" page. Any ISP could use it, and make use of hidden
fields to enable/disable certain features (like 'user port 587 for
outbound smtp', 'enable TLS', 'use full email address as username',
'use smtp.server.com for outbound email', etc.). The end user could
enter their name, email address and email client and get a one-page
printout instructing them on how to set everything up.
A better idea... The most of probably use qmail because there is vpopmail.
What about rewriting around vpopmail a modern, robust and
customizable MTA that does not force us to be acrobats in order to
add functionalities to qmail?
First step would be to mantain the same schema and code of qmail,
rewriting all the code step by step, module after module. So, free
from Bernstein license, we could finally update and upgrade the MTA
in a serious way.
