[Mimedefang] Allowing only certain sender/recipient pairs

List,

I have been asked to investigate setting up a solution to allow only certain
senders... to email only certain recipients, with any non-approved
sender/recipient messages being rejected.  It sounds like the company wants
to look into a "deny-all except that which is specifically allowed"
framework for email.

Has anyone ever set up something like this?  What database types were used
to contain the lookup tables for valid sender/recipient pairs?  What kind of
performance hits were encountered?  And I assume "stream by recipient" was
needed to allow a message to be passed to an allowed user, yet not passed to
a disallowed recipient.  What kinds of problems did that create (aside from
the obvious "one message cc'd to 10 people in becomes 10 messages out" kind
of scenario)?

David - Is this a feature available in the Can-It products?

Thanks all, for any input.
