Spearate Gnats and Mail Servers?

[nick]

Hi.  I want to setup Gnats and Gnatsweb.  I have done it once before
when our company mail and web-servers were the same machine.  Now they
are different, so am having some difficultly understanding the role of
gnatsd for submitting problems.

Is it possible to have the gnat's aliases and client utilities
(queue-pr) on the mailserver, and have these utilities contact gnatsd on
the internal gnats/web server?

Thanks,

nick
