1. Probably not. If your Exchange faces the Internet, it should reject the relay attempt during the RCPT TO: command, so the messages won't be accepted for delivery and therefore they won't be NDRed. 2. Yes. 3. If dfg.com is your domain then it's normal spam to automatically generated addresses.

Domain in question is DFG.com I've just taken over a site's Exchange server and have noticed something strange. It's been sometime since I had to play with Exchange this deep but the Queues on my IMS keep filling up with 1000's of emails. We're not an Open Relay that I can tell (I've tested) but there's just a ton of 'Outbound Message Awaiting Delivery' with originator <> and Destination Host of different .com's. There is a ton of Inbound Mail Failures in the 'Admin' mailbox for delivery failures as well. My three questions are: 1) Are these messages that are trying to relay but failing? 2) If so, are they just going to sit in the Queue for the default time? 3) For the Inbound Mail Failures, a lot of them are going to bogus addresses like [EMAIL PROTECTED] or [EMAIL PROTECTED] Where are these all coming from? Thanks in advance. Cheers, Tony _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Web Interface: http://intm-dl.sparklist.com/cgi-bin/lyris.pl?enter=exchange&text_mode=&lang =english To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Web Interface: http://intm-dl.sparklist.com/cgi-bin/lyris.pl?enter=exchange&text_mode=&lang=english To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED]
