If this is the cause, then they have changed implementation. When
they first started blocking dynamic IPs, you received a SMTP error
message with an explanation. This looks like they are now blocking in
a firewall/router.

Just for giggles, I removed my transport entry and sent a test
message. Yep, syslog messages like those cited. So the fix is to
route AOL thru your ISP's SMTP server. Add this line to
/etc/postfix/transport with obvious substitution:

aol.com smtp:[smtp-server.my.isp.com]

Run "postmap transport", be sure a line like this is in main.cf:

transport_maps = hash:/etc/postfix/transport

and restart Postfix. And to save finding out the hard way that
several subscribers to this list do the same thing, add the following
lines to /etc/postfix/transport:

weird.com smtp:[smtp-server.my.isp.com]
johnpeach.com smtp:[smtp-server.my.isp.com]

This is starting to be a Frequently Asked Question.

HTH,
