The websites can be accomplished with a front-end webserver that proxies
the requests to the "real" servers.  With Apache, you can do this with 
the ProxyPass and ProxyPassReverse directives.

The email can be accomplished depending on your mail server.  I believe
that Cyrus and Courier support what you want.  I am sure that there are
others as well.

In both cases, however, you want to take some action based on some
application-level notion of the content.  Shorewall has no notion of
this, and consequently cannot help you.
