I've been monitoring our edge server and have noticed several emails that are queued in exchange 2010 with the following information:
Identity: EDGE-SERVER\184887\329291
Subject: Undeliverable: Company Representative Needed
Internet Message ID: <aab2866e-91fd-4b48-b119-2ef96f0a2d92@my_company.com>
From Address: <>
Status: Ready
Size (KB): 11
Message Source Name: SMTP:Default internal receive connector EDGE-SERVER
Source IP: xx.xx.xx.xx
SCL: -1
Date Received: 12/4/2012 4:54:53 PM

Last Error: 400 4.4.7 Message delayed
Queue ID: EDGE-SERVER\184887
Recipients: apache@linux-green.nanuminet.com
I cannot trace where these emails came from. Are these potential spam mails within our internal network? If they are, how can i trace the source or prevent these from queuing in our exchange servers?
I hope you can help me guys. Thanks a lot!
