  • Exchange 2003 not receiving messages from some Exchange 2007 servers.

    Hello,

    In the last 2 months 4 of our clients have reported not getting through to our email addresses. Three are using a hosted Exchange 2007 environment. One hosts theor own Exchange server. The NDR is "Exchange can not deliver the message and will stop trying". We receive 100's of messages a day without issue. We are running Exchange 2003 SP2, Watchguard XTM 22 firewall, Trend Micro Worry Free Advanced AV. At least two of the clients cannot telnet to our port 25.

    Thank you in advance for any assistance.

                There should be more than that, in a lighter colour text immediately below the "Sent by..."

                    That is a timeout message, which is close to useless.
                    Doing a telnet test to exchange.llis.com it isn't an Exchange server answering the SMTP traffic, it is something else. Whatever is answering the email is the cause of the problems.

                      When I do a telnet from my home office I get "220 exchange.llis.com ESMTP Service ready"

                      That is not an Exchange connection?

                        No.
                        Just because it says its name is Exchange, doesn't mean it is Exchange.

                        An Exchange server answers like this:

                        220 server.exch.local Microsoft ESMTP MAIL Service ready at Fri, 13 Jul 2012 22:40:32 +0100

                        Even if the headers were munged, it doesn't answer in the way that I would expect. Exchange accepts "ehlo" on its own, that server wants "ehlo host.example.com".

                        It isn't Exchange.

                          Thank you Simon...

                          Is it possible our Exchange server has some configuration issues?

                          We have 22 users who send and receive 100's of emails a day so our DNS settings and our network setup is at least partially correct. we only appear to be having these issues with 4 clients who use Exchange 2007. They are important clients so we need to get this resolved.

                          Thank you for any more assistance you can offer.

                            As email is not being answered by Exchange, I doubt whether it is Exchange with the issue. You have outlined other products in use, in my experience most issues with email delivery are not caused by Exchange, but by third party products.

                            I wouldn't even touch Exchange until I have ruled out third party products - anti-virus and anti-spam. Unfortunately due to the way they integrate with Exchange, they have to be removed and the server rebooted to prove they are not the cause of any problems. Disabling them is not enough.
                            Firewalls should be checked to ensure they are not scanning SMTP traffic or providing SMTP filtering of any kind.

                            Simon.
