Messages bouncing between two servers

[preety]

Here's the setup - Two sites, one in London and the other in Liverpool. Each site has SBS2000 running Exchange 2000. The London site picks up a standard pop3 mailbox (single email address -London@domain.co.uk ). The Liverpool site picks up a similar account - Liverpool@domain.co.uk plus an unlimted alias pop3 account - *@domain.co.uk. Filters have been put on the unlimited alias accounts at the isp site (filtering on the "to,cc and bcc fields) , so that some addresses get re-routed to the London@domain.co.uk mailbox (to facilitate individual email addresses for the london site) The problem is when the an e-mail is sent to someone at the London site and the Liverpool site. The intended recipients get the message but errors are also generated.
The error message on the admins account on each server is "A configuration error in the e-mail system caused the message to bounce between two servers or to be forwarded between two recipients". The sender receives the following message "This is an automatically generated Delivery Status
Notification. Unable to deliver message to the following recipients, because the message was forwarded more than the maximum allowed times. This could indicate a mail loop".
Occasionally when anyone at domain.co.uk sends out a message they also get the following - A configuration error in the e-mail system caused the message to bounce between two servers or to be forwarded between two recipients. Contact your administrator.

If both sites have a permanent link to the Net, send all mail to Liverpool and have London pick up their mail from you. Then you don't need rerouting.

Exactly how this works will depend on the systems you have in house and the way the ISP works, but if it is just one POP3 that is outside the building, there should be a way to get it working...

London site does not have a permanent Internet connection only a standard dial-up connection.
