If you have a Linux box as a firewall/gateway also acting as the mail server,
how do you stop external people sending mail to an alias that is supposed to
be for internal use only (e.g. all_staff)?
IMHO that's MTA specific. In exim (which is what I use) I'd have
two separate routers, one for checking an alias file (or DB) for
aliases that can be accessed by anyone, and another for checking
another file (or DB) for those "internal" aliases with a
condition that sender_domains = +localdomains (i.e that the
sender's domain exists in my list of localdomains).
What MTA do u happen to be attempting this with?

eh.. I didn't know there was a Kanjokya Street - I'd even assumed
KYM-NET was on Bukoto street but I guess I stand corrected.
