Hey all,
I'm very new to sendmail and also pretty new with Exchange. I have an Exchange server that uses a sendmail smarthost to send external messages. We got everything set up great and running. Messages seemed to be routing to internet addresses just fine. As useage started to pick up I started to notice messages not getting out and stacking up in the que. in the /var/spool/mqueue directory you can see about 3 to 10 per day stack up and eventually delete with the Mailer Daemon notification back to root.
I suspect a routing issue since so many messages do get out and to the same destination domains as others that don't. And I think perhaps the routing problem may be due to having more than one route to the internet. Could be firewall, could be something else.
But I would assume that if a message is going to retried for delivery, it would just be sent to the first available route. But does it store the previous route for the next retry?
It's a big operation and I have no controls over the firewalls or routing so I have to make my case that there could be a problem. Not being up on terminology isn't helping me either... lol.
Any ideas?
