AOL 421 errors
We've noticed a surge in 421 e-mail errors from AOL.
Message soft bounced for '###@aol.com', '4.3.2 - Not accepting messages at this time ('421', [': (DYN:T1) http://postmaster.info.aol.com/errors/421dynt1.html', 'SERVICE NOT AVAILABLE']) '
It seems as though they've tightened down their policies.
We're pretty good at preventing spam with our IronPort
anti-spam gateways and internal policies.
We've also subscribed to their FBL notification service.
I'm surprised at the types of messages AOL customers consider
as spam. Anything and everything: university admission acceptance
notices; instructor class assignments; photos from friends; etc.
