We had a terrible day today in where we had to restore from a backup. Our exchange 2003 system was corrupt. Nothing was working, etc..
Because of this now after we "fix" the email server. We cannot telnet to port 25 from the outside. In another words external email is not coming in. Internally the email server is fine. We can telnet to it using port 25.
I need to know what could be wrong with the filtering systems that we have here. We have first a cisco ASA firewall then a smart host Linux box that run spamassin. Both were fine until the exchange corruption.
There was nothing wrong with the firewall until today. It is extremely bizarre the chain of events.
Any thoughts? I have attached the ASA 5510 configuration for your review.
Again we need to telnet to port 25 our email server from the outside.
