For about a month, we haven't received emails from a specific location. These are notification emails that of course are sent from an address that is not monitored. From what I've been told, these emails stopped arriving when I enabled the anti-spam in exchange 2007. I had a threshold of 9 set to be rejected, and a threshold of 6 set to be quarantined. I then took off the reject message, and still no emails (not even in quarantine). Then yesterday I completely disabled the spam filter altogether, and still no emails. I have a ticket in with the place that is sending these notifications, and they say according to their message log messages are being sent out. Is there anything I can do on my end to help troubleshoot this?
Don't know if the two are related, but also other internal notification emails are not being received as well. These come from our timecard program, but ever since I switched the server they are supposed to be sent through, they are not arriving. I even switched back, and still no notifications.
