That's not autoforwarding, that's alternate recipient using contacts. I don't understand what you're calling a peer domain.

Could you expand a little? We have some forwarding set via AD/Exchange user properties rather than Outlook rules. The peer domain is in the same AD forest - sorry if I didn't make that clear - so is forwarding issue a red herring?

If you're allowing that, then you are reaping what you sow.

Would a temporary block for my own domain help to get rid of this message?

Christopher (UCL-MSD) Sent: Thursday, November 18, 2004 8:57 AM To: Exchange Discussions Subject: Mail Loop on Ex2k Adv or How to Crash Exchange Hi, A user sent a message to '=SMTP:[EMAIL PROTECTED]' where domain is a peer domain with a now non-existent Exchange server. How this happened is unclear but user says 'my typing was changed automatically' so the address is retrieved from AD or users contacts. The result is constant looping behaviour that sees the transaction logs growing at 70MB per minute which filled the 5gb log partition and shut down all the mail stores. The message is not in the queues. Dismounting the user's mail store stops the looping, other mail stores are unaffected. If the mail store re-mounted briefly tracking log shows the message with repeat SMTP: Message Submitted to Advanced Queuing SMTP: Stated Message Submission to Advanced Queue SMTP: Message Submitted to Categorizer Any ideas on how to cure this?
