Massive SPAM Increase

Hi,I don't know if I'm a target of some SPAM attack or if it is just business as usual.
In the past day or two, I started seeing a lot ( ~ 3000/day ) bounces from SPAMers forging my domain in their "From:" address. I probably have over 10000 bounces now.
However, what is unusual is the following: - The actual spam is sent From "domain@domain" (where domain is my domain).- The actual spam headers attempt to forget my mail server's IP and FQDN in the "Received: " headers to make it look like I actually sent it. - Some spam messages also contain references to the dns server for my domain in them.
Most of the IP addresses look like that a large group in Poland is doing this....
And most of the messages either have the "TheBat" in "X-Mailer" or the MessageID.
I'm used to forged SPAM, but not on this scale... -Alex ------------------------------------------------------------------------------ This List Sponsored by: Black HatAttend the Black Hat Briefings & Training USA, July 29-August 3 in Las Vegas.
