Weird SMTP Queues

Post by PQ » Sat, 20 Dec 2003 06:25:57


On my Exchange 2000 server there are several SMTP queues
that appear to be spam relay attempts but as I have
checked the server from several sources to verify we are
not an open relay I am wondering how to get rid of these
strange queues completely. It appears that the server
accepts the message but will not relay it - just dumps
it. How can I stop this altogether? I'd appreciate any
assistance - Thanks!

Hi PQ,

If a Spammer was using your Server as a Relay you would have more than just
a few queues. Enumerate the messages in these queues and take a look at
them. They are probably NDR's going back to bogus domains as a result of
inbound Spam mail going to non existent users in your domain.

Hope this helps,

Patrick -
When I enumerate these messages, there's nothing there. I
figured this was what was happening but wanted to make
sure I had covered all my bases. Thanks!
