Hello,

I have been getting this error from our exchange 2003 server randomly since
we migrated from a exchange 2000 server. We use our exchange server with
outlook 2000, and do NOT host our own external email. here is the error.

A non-delivery report with a status code of 5.3.5 was generated for
recipient rfc822;<email address> (Message-ID
33516BB6CBBC87488E59F3E8735D6CF4148085@<Servername>).

Causes: A looping condition was detected. (The server is configured to route
mail back to itself). If you have multiple SMTP Virtual Servers configured
on your Exchange server, make sure they are defined by a unique incoming
port and that the outgoing SMTP port configuration is valid to avoid looping
between local virtual servers.

Solution: Check the configuration of the virtual serverÆs connectors for
loops and ensure each virtual server is defined by a unique incoming port.



Any help would be great.

Thanks
