This does not allow amavisd to distinguish between incoming,
outgoing, and internal mail. Depending on your intended use
of features, this may or may not be important.

Yes, this is normal. Inbound, and internal-to-internal mail
is checked for pen pals, matching it to a previous mail
originating from inside.

Is not even checked, or just does not find a matching record in a database?
Turn up log level to 4 and grep the log for a string 'penpals:' .
(the more important of these log entries are at log level 2, one is
at level 3, the rest is at 4; log level 5 would also show SQL clauses
being executed).

Incoming and internal is supposed to be checked, outgoing not.

- all recipients matching @local_domains_maps (except when sender is the
same as recipient) should result in a penpals SQL query;
- for a query to match some previous mail in the opposite direction,
that mail must have exactly matching sender and recipient address
(swapped), or at least have a matching previous sender _and_
and match on Message-ID. Make sure virtual_alias_maps and canonical
(when used) is not causing mismatches.
- to save cycles, a ham message with low spam score which does not need
pen pals help is not checked, and on the other extreme, an high
scoring spam which would not have a chance of being saved
even by a maximum pen pals contribution, is not checked either.
To override these two optimization steps for test purposes, set:
$penpals_threshold_low = undef;
$penpals_threshold_high = undef;
- one additional condition: unauthenticated senders from outside (i.e.
not having IP matching @mynetworks) _and_ using a local domain address
do not receive a pen pals bonus. Make sure your @mynetworks is correct.
