So, based on the assumption that 'SMTP AUTH' is the way to go I configured
AUTH_REQUIRED=1 and ESMTPAUTH="LOGIN CRAM-MD5".
This seemed to work fine for outgoing mail, *however* all incoming mail
stopped. It seems all the SMTP servers out there had to authorize with our
server before it would accept mail.
Have I misunderstood the purpose of SMTP AUTH or have I messed up the
Both. Sorta. SMTP AUTH is *specifically* for allowing clients to relay
when they are not listed in the IP based access list. In other words:
they were already required to authenticate to relay mail.
AUTH_REQUIRED makes AUTH *required*. Don't turn that on, and everything
will work the way you want it to.
