Exchange 2007 - Sorry MS keeps messing with the site and it is no longer listed so yes it goes in the 2013 bucket. :)
So I had a nice 24 hour session of attempting to find out why my hubs kept going up and down. I had to keep restarting the transport services. Turns out a user attempted to send a 1.5 gb file from one of our Unix systems. This would all be via SMTP.
We have a 50mb limit set on all connectors and so on.
I would assume the message would simply have been bounced and never caused a problem. Luckily the network team was able to identify where this persistent connection trying to send this email was coming from.
So the question is why isn't Exchange honoring the limits already setup?
