Receiving e-mails a lot of times

[Stoemp]

Hi

I'm using Exchange Server 2003 as part of Windows 2003 SBE. As anti-virus I'm using Trend Micro.

Here's my problem:

I have some mails that keep being delivered in my mailbox, several days after the original message has been sent. When I look to my antivirus, these copies don't pass through it, so it seems that they're in some kind of loop in my Exchange server. How can I stop these messages from being delivered over and over again?

Thanks

S.
