So they were messing with the firewall yesterday.
At a point all outbound email stopped and then it went ok.
I found out that ALL UDP has now been blocked (except for DNS).
NOW all outbound email to aol.com is queued.
When I cancelled one I got back...

(front-end server name) #4.3.2
All other outbound email is fine
Just AOL.com (inbound is fine)
When I telnet to the server and try outbound to aol.com it works fine.
Now SMTP is port 25 but is it just TCP or both TCP/UDP? Remember as far as
I know this is only stopping email going to aol.com
As far as you know? Have you looked at the logs?
AOL will drop many SMTP servers, especially those on broadband or
dynamic IP addresses.
There is no UDP involved in SMTP traffic. Inbound you should only
need to open port 25.
