Can't receive incoming email from external addresses on Exchange 2003
Posted on 2011-09-03
I'm having issues with our exchange server where we can send emails internally and externally and receive emails internally, but we are not able to receive any emails from external sources. The external sources doesn't seem to be getting any type of bounce back either. I did some searches using message tracking and there is no trace of these emails hitting our server.
What's the first thing that I should look at. Is it safe to rule out DNS if I can send emails out?
