Exchange 2000 for SBS creating duplicate emails

We recently had to change our server box and reinstall Server 2000 SBS. The Exchange settings were moved to the new installation, which were almost all default settings. Since the new box went live, email messages are being duplicated based on the number of recipients from the domain. For example; for an email with 10 recipients, 8 are from our domain. For each of those 8 instances, the email is essentially "bouncing" off our server and being sent to every recipient again. For the 2 recipients that are not from our domain, they will receive that email 8 times - one for each of the recipients from our domain.

Are you using the POP3 connector?

Yes - and that is set up the same as the old server as well. I supposed it is possible I missed something, but I went through each properties menu with a fine toothed combed so I would be surprised if that were the case.

There is a problem with the POP3 connector which will cause this behaviour. You need to ensure that the server is fully patched. Use Microsoft Update to check (not Windows Update which only does Windows). I think Microsoft Update will cover Exchange 2000.

Any reason why you are using the POP3 connector and not SMTP delivery which is how Exchange is designed to work?

I have been watching behavior of the email queue and haven't see a change since ensuring Exchange is fully patched. FYI, I'm using the POP3 at the instruction of our ISP. All emails that are routed to *@ourdomain.com are dumped into a single queue. Our POP3 then downloads them and they are routed internally according to address. I wasn't aware this was possible via SMTP. Any advice would be greatly appreciated.

Your ISP doesn't know what they are on about. Exchange is not designed to be used with POP3 connectors. It is designed to have email delivered directly by SMTP. However the problem you have is that Exchange 2000 is unable to defend itself against a number of common attacks, such as NDR attacks. If you cannot upgrade then I would be looking at putting a third party tool such as Vamsoft ORF on to the server.

If you have a static IP address then get the MX records change to a host pointing at your own IP address and do away with the horrible POP3 connector.

Thanks - this is the answer I was looking for. The ISP doesn't have any Exchange experience and it's my weak link as well, but have learned a lot in the past few months. Something has always struck me as wrong about the current config. Since reading this, I found some good supporting documentation that will assist. Thanks again -
