Compile ZMailer with TCP wrapper support and enable
it in smtpserver config. As I know some functionality
required by you is available in this library.

I rewriten fully perl support, added postgrey support in smtpserver
and added SRS support, header rewriting and much more in router.
Additionaly, I corrected some bugs. Currently I am testing my big
patch and I am going to publish it at the beginning of September.
However, ... this patch is for 2.99.57.pre3... but I think it
could be easliy ported to CVS version.
