I have changed the MX record of a domain to point to our firewall but any email sent to the domain is not being picked up by the mail server. What could be wrong please?
Need to get this sorted out ASAP, so all help much appreciated...
You need to find out whether the problem is with the firewall or the mail server
Does the firewall have the public facing IP set to accept traffice on port 21? Is the firewalls inbound tunnel pointing at the correct internal IP? Can you telnet into your mail server from the Internet? If you port scan your mail server from the internal network is port 21 active?
what mail server are you running Exchange??
