PMX Filtering

Hi,

I'm using Puremessage for UNIX version 5.6.0.

I want to know if PMX if capable to work like a mail anti-bombing aplication.

What I want to do:

  - Filter messages with 30 or more recipients from a certain domain using a black list what contains the domains I don't want they send messages with more than 30 recipients. If the server receives a message with more than 30 recipients but the domain of the sender is not in the black list, the message will be delivered.

It's that possible?

Thanks
