I have Exchange 5.5 set up on a 2000 server inside a PIX firewall. I have opened conduits for tcp traffice on ports 25, 110, 135, 143, 102, 389, 993 & 995. I can receive mail from clients like Eudora, but not from Outlook/exchange users on other Exchange sites not related to me. Everything works internally and I can receive Eudora mail from outside, but not Exchange mail. Sent mail bounces back to user with message "Your message did not reach some or all of the intended recipients.
" and"The recipient name is not recognized"
and "User not local; please try "

Any ideas?
Thanks,

I am sorry, and I am sure you passed on a good thought, but as it happens the problem was not related to Exchange or the Firewall. The service handing DNS for our client had made a mistake on one of their record entries and that was what was causing the problem. Thanks for trying.

RE 1st response: I looked at that Q155831. Perhaps I'm just thick, but I would have thought that only applied to Exchange clients trying to remotely connect to my server. What I have is clients of someone else's server can't send mail to me. Wouldn't that just be SMTP between the 2 Exch servers?
