I'm on Exchange 2003.  Only certain domains fail to send. Comcast is fine. Yahoo is fine.
I'm not sure what else to explain here.  There are no failed delivery messages.

Thanks

The problem is most likely is a Reverse DNS issue call AOL postmaster or do a Reverse DNS lookup www.dnsstuff.com to see if your resolving correctly.

I added a PTR Record exists and I get a reverse DNS OK.  This takes some time to replicate that would cause the emails to be slow going out?

Although most emails left the outbound queue, there are emails that still "stuck".  Any ideas what would cause this?

Thanks

You really need the NDR message that is generated when they fail. That will give the best clue.
If it is constantly the same domains, then you may have to use an SMTP Connector and route email via the ISPs SMTP server.

Here are the two messages in the Queue.  No NDR messages.

verizon.net: "The connection was dropped by the remote host"
earthlink.net "The remote server did not respond to a connection attempt."

The domains are blocking your messages. Any number of reasons why that could be. If you are sure that everything is configured correctly with regards to DNS, then you will have to use the suggestion I made above - an SMTP Connector.

Thanks Sembee....it took until 10:30am 7/20 for it all to start going out....I made no additional changes.  DNS had to replicate? <shrug>

If you had made DNS changes, then those can take time to replicate - anything up to 48 hours, if not more.
