SMTP Traffic Monitor
Posted on 2010-01-11
I'm looking for suggestions on a tool that can monitor SMTP traffic. I've used a few monitors that can ping each appliance and give me up/down alerts, but I need something that can authenticate to our system and verify delivery of a test message. The problem is that we have a fragile email filter that is technically "up" according to all monitors, but for various reasons will stop passing traffic, and will just queue all messages. Any suggestions would be appreciated. If anyone knows of a free tool that can do this, that would be preferred, but I'm interested in anyone's opinion on any tools they have used and had a good experience with.
-McAffee Secure Mail 6.7.1 (the filter that is causing problems)
-Exchange 2007 and 2003 mixed environment (has been rock solid, but messages can't get to Exchange if Secure Mail stops passing traffic)
