Whenever I try to send out to an AOL address I get a delayed message back and it doesn't go through

I have a 2003 Exchange server and I recently changed ISP's.  Got it all working, but whenever I send to an AOL address it's giving me a delayed error back and the person with an AOL address isn't getting the email.  What should I do?  All other email is going just fine.  Is there someone I can contact?

Do you get a "no permission to send to this user" or something along those lines in the SMTP bounce message? Likely your message is being bounced because your reverse DNS is not matching your domain. Ask your ISP about setting up a PTR record for you.

Try going here and see what your results are for your exchange server's IP:

reverse dns is setup.  from mxtoolbox.

OK - resolves to mail.denisonlawyers.com
 OK - Reverse DNS matches SMTP Banner
 0 seconds - Good on Connection time
Not an open relay.
 0.421 seconds - Good on Transaction time
Making Bulk Changes to Active Directory

Watch this video to see how easy it is to make mass changes to Active Directory from an external text file without using complicated scripts.


You may as well try the blacklist test on that site as well  :)

All of them say OK.  Any other suggestions?
Can you provide the headers for your NDR (bounced message)?
they will be helpful.

The following recipient(s) cannot be reached:

            This message was rejected due to the current administrative policy by the destination server.  Please retry at a later time.  If that fails, contact your system administrator.

Are there any clues in the SMTP error message?

You can try connecting to the AOL server with telnet and see what happens as you try to leave a message step by step.

Here's how if you need:

I see you beat me to it. Maybe AOL is requiring SPF records now? Just guessing.
so the error code is : #4.3.2 from the headers.

which means

Message deleted from a queue by the administrator via the Queue Viewer interface in Exchange System Manager.

Let me look that up on google.
Review this link:

On the NDR table, it refers to this:
4.3.2 Classic temporary problem, the Administrator has frozen the queue.

Check if the que is frozen?

Exchange System Manager failed to retrieve queues for the SMTP Virtual Server (error code = 0x800706BE).  Check the event log and verify that the required services are running.

This is what I get when I check the queues.  I've checked the services required and those are running.  This wasn't always like this.  I checked the queues the other day and I saw them and none of them were frozen.

Found out it was AOL's postmaster that was blocking the messages.  Emailed them and voila.
