Re: AOL rejecting hosts with no rDNS?

2004-06-24 14:09:19
We look up the PTR but don't (yet) reject if none - however frequently the SMTP
connection times out before the DNS PTR lookup does, causing high failure 
percentage
- when the PTR-less domain calls for assistance, we explain PTR and point them 
to
www.dnsstuff.com ;-)

It's configurable in many MTA's but I've not found MTA's setting policy. :-)

Generally the MTA's are configured in accordance with the organizational
owner of the MTA. ;-)

For my part I reject these out right on our mail hosts. "Get right or
get gone!" is my motto. He-he!
