Our solution was to setup a linux machine running postfix to handle outgoing
mail and change the SIMS setting for it to send all of its mail out using
this new server. The postfix server has some simple content filtering which
eliminates a lot of the virus and worm email that our customers are sending
to the internet.
That is the root of the problem. With the latest new worms and virii, we are
processing about 50 times the mail load we had in the past.
When one of our customers sent a worm with 100+ recipients and most of those
were rejected for whatever reason, many bounce messages back to our server
were generated. When there were hundreds of these outgoing worms, the number
of bounces was massive. SIMS couldn't handle it.
Once we put this server in place we were able to put all the old mail back
into the queue and SIMS chugged through it with no problems. At one point I
dropped 9,000 items into the SIMS queue and restarted SIMS. It all got
delivered.
So currently: all of our customers send to SIMS, SIMS handles local delivery
then sends all outbound messages to the postfix machine.
We are also considering adding another postfix machine to handle incoming
mail so we can filter that as well.
We want to keep SIMS as our customer facing machine becase of the scripts we
have which talk to SIMS from our filemaker database which is how we control
our network.
