RCPTHOSTS setting in tcp.rules

[ml-qmail@epigenomics.com]

Hi!

This is a patch to allow to set the location of the rcpthosts and
morercpthosts.cdb files from environment variables in the tcpserver
rules.

   return 0;
 }

We are using it to run servers for different domains on different IP
addresses within the same qmail setup.

If there is a better way to allow specific domains in specific
qmail-smtpd invocations (read: services) then please let me know.
