if you're supporting AUTH, you really should use TLS as well. otherwise you're allowing your users to send their passwords across the internet in plain text- and all it takes is one spammer with a packet sniffer to use your machine as a relay.

If you use CRAM-MD5 for the AUTH method, it's impossible to sniff the cleartext password.

I don't bet on this. If you tape the SMTP dialoge, its easy to encrypt the 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.

You should start teaching yourself. http://www.fehcom.de/qmail/smtpauth.html is your friend.

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?

Do you have considered how many changes vpopmail has undergone the last years ?
Did you ever do a code digest ?
Do you have the slightest idea how vchkpw works ?

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.

If anything needs a rewrite, its vpopmail - qmail is perfect in the way it is defined. Or course, since 1998 the requirements have changed.

In particular, most of the SMTP add-ones (as defined in the latest RFCs) are (according to my personal oppinion) - useless. We do have AC in our cars, DVD + surround sound, airbags, automatic adjusting seats - but we still use four wheels and a benzine motor, driving on badly-paved roads.

Qmail is a good car, but the road gets increasingly worse - adding DVD players to your car doesn't really help.
