My ISP is AT&T who does not offer reverse dns service.
I have exchange 2003. When I send an email to AOL.com or COMCAST.NET, their
spam filter does the reverse dns check and since at&T does not support
reverse dns, our ip address is not resolved and AOL AND COMCAST both rejects
our email.

AT&T offers reverse dns for T1 line it means I need to upgrade the service
with them and my block of ip addresses will be changed.

I would appreciate if someone please share their experience and if they have
any solution, please post it.

Thanks

Smarthost your mail through AT&T or smarthost through a 3rd party
service such as www.dyndns.org

They have default PTRs on all their IP addresses, if you have a Static 5 IP
account they will delegate. Otherwise, I think they have to host the forward
zone to do custom PTRs. Or set up their server as the Smart host.

I recently went through this with AOL and called and yelled at their email
department and they removed the block. Be sure and tell them what a stupid
policy this is. Maybe some day they will get a clue.
