Exchange 2003 SMTP Connectors RRS feed

  • General discussion

  • I support two companies that use Exchange 2003. Each of these companies has a default SMTP connector.

    These companies want to send confidential information to each other. I have setup an IPSec VPN tunnel between the two offices. I would like to setup an SMTP connector between these two companies so that they can route email destined to each other over the VPN tunnel.

    I setup the tunnel between the servers with the following settings:

    Server A

    Foward all mail through this connector: Server B IP address

    Address Space: cost 1

    Server B

    Foward all mail through this connector: Server A IP address

    Address Space: cost 1

    This worked fine for a day or two, until we noticed that other mail was backing up in the queues. This seemed to be affecting the default SMTP connector. I was forced to remove the connector.

    Please advise what I am doing wrong?

  • I was using a forwarder, so the mail was queuing under the relay server. Do I need to give a differenr cost to the default SMTP connector and the ServerB SMTP connector?

  • Use SMTP connectors instead, rather than specifying on the virtual server.

  • I am using SMTP connectors. This is what the thread is about.

  • Thats seems correct, do you know the reason or for the queues>? Did it mention this in queue viewer?

    Or in the app log?

    Are you sure it was this which caused it and not something else?

  • I wouldn't have suspected that to effect the * config.

    Strange how it worked for 1 day and then failed.

    Are you in a position to test again?
