A question submitted on SearchExchange.com
We took our exchange server down on Friday and since we brought it back up we have not received external emails.
I can telnet to our ISP SMTP server OK from the exchange server itself but no mail is going out or coming in. No changes were made to the exchange server other than a symantec ghost copy was made and some exchange services were disabled and the server was re-started. I have ensured that all services are running OK.
We have anti-spam software which I am sure is not intervening. I suspect its the cisco pix not allowing mail through.
