Distribution Groups and Spam

[biketech]

Hi everyone.

I recently set up a distribution group on my Exchange 2003 server (part of a Small Business Server 2003 package). The distribution group includes several contacts who have external SMTP addresses and a few internal users. Somehow, spammers have got their hands on the distribution group address (distrogroup@ourserver.org). Does anyone know how this is possible given that this address has not been posted in any public forum or Web site? How do spammers get ahold of this stuff? Any ideas or links to helpful threads is appreciated.

Thanks,

MG

Possibly they got a hold of it from your external users. In other words their PC gets infected from some type of trojan or spyware, steals all of their addresses (which includes the distribution address) and then you get SPAMMED.
