Suggested Feature: Submission Service

[Toni Mueller <support@oeko.net>]

Hello,

while thinking about SPAM, it occurred to me that using the submission
service could help to ease the problem. I therefore suggest that
qmail-ldap comes with a submission service. This would be a clone of
the SMTP service, but listening on the submission port and utilizing
strong access control. The rule file would be named eg.
qmail-sumission.rules, and access control could look like this (I have
it on my default "accept" rule):

SMTPAUTH="TLSREQUIRED",AUTHREQUIRED="1".

What do you think?


Best,
