Can you send us the log lines of your server when the relay is denied? If
you don't have any, it is because the relay is not even pointing your
server. So at the end it is a problem of the DNS resolving the FQDN of the
smtp set at the outlook properties.

Any logs at your server? If you are not getting any logs of this email
account (when sending) problem is again with the DNS or something alike.
Ping your smtp from that computer to make sure that the FQDN is resolving
correctly. Make sure it is using the proper ISP DNS and make sure it solves
the domains involved correctly

AOL doesn't allow to relay in any email server other than their own.. and
worst of all you have to use AOL email client software to relay on their own
mail server. As far as I know there is no way to send email via port 25
using AOL dialup connection. I have that problem with a customer in the
past. I called AOL and they confirmed what I just said above.

Viruses.. I don't think so.. Imail config.. I don't think so either. Let's
see the logs and how those specific computers are solving the domains and we
will see from there.

That is why I am very optimistic about the DNS check of those computers..
and of course of the logs. One test you can do is to change the SMTP
outgoing server by the real IP address of your server.. just for your
tests.. just to make sure they are using your Imail server.

Study your Imail logs the minutes before the SMTP restarts to see if you can
see any abnormal situation. Compare that to other smtp restarts and try to
find a connection that may be the cause of the problem.
