What about the most recent qmail (1.03-3.1) package in the development
tree. It has a patch that forces encryption before authentication.

I have my own OpenVAS server to test my Qmail server for security. One
of the things I get as a “medium” warning is
“The remote host is running SMTP server that allows cleartext logins
over unencrypted connections.”
It’s saying we allow LOGIN and PLAIN for SMTP while supporting the
“STARTTLS” command.
I’ve been looking at the /var/qmail/supervise/smtp/run file but don’t
see how to turn off the LOGIN and PLAIN for SMTP [or enforce STARTTLS
instead].
Ideas on how to fix this?

p.s. if anyone needs a good scanning tool, I highly recommend OpenVAS.
After all, like Qmail, it’s freeware [or has a free version]
