My SMTP gateway (installed on windows 2008 R2) is getting rejected by .How do I enable SMTP logging so I can troubleshoot the issue?
1. mxtoolbox doesn't show any smpt errors on my domain
2. when I try to telnet port 25 it will not connect , while connects fine to any other server
3. I also have 2003 based (second) SMTP gateway which connects fine to 25
both SPF records are good
any ideas?

    if you're not able to open a TCP session on port 25 then that's where I'd start instead of logging SMTP.  I'm able to telnet 25 from here to that address.

    i am not sure if you really read my question,
    that was my question how to start SMTP logging on Win r2 2008. I've seen posting suggestion to add ODBC server role hoever I don't see this option on my box

    Accepted Solution

    Here is a step by step on installing the odbc logging feature:

    Once you have enabled that feature follow the steps below to get logging working:

    1) Stop / Start the SMTP Service
    2) Verify your SMTP service is configured for logging.  It's not on by default.
    3) Try a local telnet test (assuming the telnet client is installed)
    4) Look at your log folder.
