Exchange Queues

[sdgman500]

I have an Exchange 2003 mail server with Symantec SMS 5.0 running on it.

When I look at my queues in System Manager, I have like over 300 domains in the queue. That doesn't seem right. Majority of them are like:
aaaoklahoma.com
beeezley.com
and so on. Just real goofy domains.

Do I have a workstation sending spam out? I don't think I have "reply to send" set in my Anti spam software.

How and where are all these domains/emails coming from? Where do I even begin looking?

Thanks,
Shane

You are most likely sending out NDRs for invalid addresses from received spam. Normally you can ignore these.

You can suppress this by changing the global settings to not send external NDRs, but that might not be a good business practice.

Someone could be attempting to relay through your server. I would recommend RECIPIENT, SENDER, and CONNECTION filtering - all parts of SP2
