The site here does something like this, using smartuser director:
okayuser:
local_parts = lsearch;/conf/mail/users,
driver = smartuser,
domains = local.domain.org,
more = false,
transport = smtp,
verify = true;
That's extracted from the configure file for the mailserver on
Internet side of things, slightly edited. Userids that can send
and receive Internet mail are in the /conf/mail/users file. Anybody
else will bounce with an "unknown local part".
That mailserver can talk only to an internal mailserver. IP filters
and IP routers make sure that no other internal machine can get
to the Internet, so bypassing the mail configuration is not a
viable option, short of rewiring the site.
