My client has a PIX 506E with Ver 6.3 running. Up until 3 days ago all was running. He deleted 5 lines of code concerning another area of the PIX. Mail has stopped working. I have checked the config and there is both a static mapping of an outside address to an inside address and an ACL permiting smtp to flow from the outside address to the correct internal address. I am unable to see any connection attempt to the mail server. The ACL shows 0 hits. I get a failure when I try to telnet to the server on port 25. The users are able to connect to outside internet sites. I am also able to connect to a PC onsite using teamviewer. Any ideas on how to trace this issue and fix it?
