Routing group connector mail stuck exchange 2003 with 2007

Posted on 2007-07-23

I have an Exchange 2003 running on Windows 2003 server.  I have set up an Exchange 2007 server on windows 2003 x64.  I have moved over 1 mailbox.  All mail was being sent and received ok.  Now this mailbox's incomming mail has stopped and the mail gets stuck in the Routing group connector.  If I reboot the server all the mail gets cleared and received ok, so I feel like I must have it set up ok.  But then I send another mail to it and it gets stuck again.  It can send mail ok.  I have a smart host in internet mail connector and i have added the routing group to the internet email connector.  All the 2003 mailboxes are working fine.  My intention is to migrate all mailboxes over to 2007 and stop 2003 exchange.

    If the messages clear after a reboot that is classic third party interference. AV software would be the first place to look. Make sure that any SMTP Scanning has been disabled.

    I have Symantec groupworks AV and GFI mail.
    In Syamantec should i turn off exchange monitoring?
    In GFI should i turn off outbound mail monitoring?
    Is there anywhere else that does SMTP scanning?
    Thanks Terry

    Both of those products have caused problems in the past. Unfortunately due to the way that they integrate with Exchange the only way to ensure that they are not he cause is to remove them.
    However what I was more interested in was any kind of desktop AV. A number of these have SMTP protection, and will allow connections to remote servers (off site) but will block traffic to local IP addresses as an anti virus measure.

    Yes that's it.  I have left Symantec exchange monitoring on, but turned off file checking on 2003 server.  Mail now flowing great.
    thanks Terry
