[Snort-sigs] Using snort to stop SMTP dictionary attacks

Hey guys,

I'm fairly new to this list so I apologize if I do something newbieish.

I've searched dejanews already and have found nothing, so I am here.

I would like to know if there is a way to use snort to detect SMTP
address harvesting attempts, and alert on them, and also do TCP resets
of the SMTP session when it detects a harvesting attempt.

I think something like this would be VERY valuable to have.

I'm using Snort 2.0 with MySQL, in conjunction with Demarc PureSecure.

Thanks in advance!
Steve Cody
