Re: [AMaViS-user] policy bank for local recipients.

Can't be done. A message can have multiple recipients.

A policy bank applies to a message processing as a whole,
it can conceptually only be loaded on some property that pertains
to a message as a whole, such as sender's IP address,
sender address, incoming port number, ...

A mechanism that applies per-recipient is *_maps lookups.

Differenting outgoing and all-internal from incoming mail
is based on sending client's IP address (@mynetworks or port-based).

- incoming: foreign sending client
- outgoing: internal sending client and non-local recipient
- internal: internal sending client and local recipient

(authenticatd mail from roaming users should preferably
be handled the same as mail from internal hosts)

Yes, that is the way to go.

Also, authenticated mail from roaming clients should be sent
to the filtering port, just as mail originating from inside.


If using a policy bank other than MYNETS for such a purpose,
don't forget to also set:
originating => 1,
key/value pair in such a policy bank.

(with MYNETS this is turned on implicitly for backwards
compatibility; it doesn't hurt to be explicit there too)
