Hi all
Just to clarify some points
They are running an IMAP server with SASL login for remote users
IMAP let's you get mail from your account. So it's really not related to
your problem.
You'd have to use SMTP authentication so when one wants to send mail
from [email protected] to [email protected] or [email protected],
one has to use IP inside my_networks or has to authenticate using SASL
authentication with SMTP session. So this will certainly stop spam from
[email protected] to [email protected], but please read whole thread - you
should be aware of possible risks.
