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 configuration?

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.
