[H-GEN] Feasibility of setting up a 'Members only' e-mail address on a linux box?

Sorry I should have been clearer.  Basically what I'm after is a central
(not per-user) way of altering/marking/moving e-mail sent from
particular e-mail addresses (those of our members - roughly 1500 e-mail
address) so that they can be prioritised above the gazillions of others
my organisation receives.

I had considered using the e-mail clients filtering (we use t'bird) but
didn't want the hassle of setting this up on each staff members PC
(sysadmin isn't my job - I just happen to know enough to be dangerous
and so am the designated, albeit reluctant and inadequate 'IT guru').
Also I don't think it's possible to get t'bird to filter based on the
contents of a file (if (From: in /linux_box/share/whiltelist) then set
priority = high).

So my initial thought was some sort of whitelist setup to block
non-members emails to a specific members-only e-mail address.  I've
since remembered that our mail server uses procmail as the MDA - so the
whitelist idea will work, but it needn't be just for a specific e-mail
address.  And with a bit of googling I've got some ideas of what the
recipe for doing this would look like.

Apologies if I've wasted anyones time - I really shouldn't think aloud
on e-mail, it's a bad enough habit in the physical world, let alone the
virtual one.

Cheers,

David
