Thanks for the quick reply Norman

I don't think I read the matcher docs closely enough!

With regard to our current setup, we use Postfix as our frontline MTA so I am 
primarily looking at James as a content filter behind that. As you say though it 
does sound like it can fit our requirements so I will definitely be doing 
further research on it.

Thanks again.

Yeah you could use the RecipientIsRegex matcher for that. See:
http://james.apache.org/server/2.3.2/provided_matchers.html

Sure I did something similar at my old employer. We stored stuff in db
and lookup the values in a given matcher/mailet.

With current trunk you even can do a lot of this in the smtp protocol.
So you could reject email before you even spool it etc.

Bye,
Norman

Ps: Yes JAMES sounds like a good fit for you needs
