You should have the server name in there, amongst other things, 250-STARTTLS and 250-AUTH being the other most important ones.

Stop sendmail and prevent it from starting, then re-install postfix. This guide might help...

AUTH, TLS and SASL is all fixed,

But I'm still getting the error with vBulletin.

interestingly enough, it's rejecting the MX tools I'm using and showing the log of rejecting, but shows no log of rejecting vBulletin at all.

SMTP Reverse Banner Check failing wouldn't have anything to do with not being able to send messages? Right?

Changing the smtp listening port to 587 did absolutely nothing...
