Hello Experts!

A couple days ago i had a serious exchange 2003 problem in which i was being attacked via an "authenticated relay", as Expert  AlanHardisty told me http://www.experts-exchange.com/Software/Server_Software/Email_Servers/Exchange/Q_26858960.html.

I have applied Recepient Filtering,Sender Filtering, SenderID filtering, and i have disabled the basic authentication completely for the time being from the smtp virtual connector.

In the sender filtering i just manually inserted the postmaster@mydomain to the list.
does anyone have any ideas?

Thanks.

Who are the recipients of the messages from Postmaster?

Blocking mail from Postmaster@yourdomain.com is futile - you won't receive any mail and if you added that thinking it would stop the messages in the queue - then it won't unfortunately.

Do you receive your mail directly to your server or via a 3rd party that filters mail for you?
