Sendmail v Qmail & RBLs

Hello everyone,

This post is somewhat off-topic, but still a technical question none-the-less.

I'm working on setting up an mail server that will act as a gateway between the outside world and an exchange server.

This gateway mail server needs to be able to do the following:

* Message filtering (for attachements, viruses, etc) using procmail or the like
* Reference RBLs such as ORBs for open relays and spammers
* Run on Linux

Right now I'm looking at Sendmail and Qmail, as I've used and am familiar with both. I know both can work with Procmail on a local-user basis, but all of the recipients are on the exchange server.

Any hints, tips and links are greatly appreciated...

Thanks,
C
