This was a good test, if I use the sender domain of the messages I am saying
are spam because they are the messages that lock up in the queue and remain
sendmail -f colvdiyfqnaturalfoodchain.com testaccountclientserver.net <
This times out sending to the exchange server.
If I take the same exact entry but put my domain as the sender like so:
sendmail -f colvdiyfqmydomainname.com testaccountclientserver.net <
It works perfectly with NO hung connections on either side.
I tried this with 2 different domains that were from messages that were
locked up in the queue on the postfix side with the same results.
