ProxSMTP is a flexible tool that allows you to reject, change or log email based
on arbitrary critera. It accepts SMTP connections and forwards the SMTP commands and responses
to another SMTP server. The 'DATA' email body is intercepted and filtered before
forwarding.
You need to be able to write the filtering scripts that integrate it with your particular needs. If you're looking for something that does virus filtering, take a look at which behaves similarly and uses a similar code base.
I wrote this with the mail server in mind. how to configure it as a Postfix Content Filter.
ProxSMTP can also be used as a to filter an entire network's SMTP traffic at the router.
