There is no direct relationship between mynetworks in amavisd,
and the concept of trusted/internal/msa networks in
SpamAssassin,
these serve a different purpose (although they are
related).
The mynetworks allows amavisd to differentiate between
mail originating
from inside, from the rest. It allows for triggering policy
banks,
allowing disclaimers to be inserted, and for the Pen Pals
feature to
work as intended. Through policy banks one may then apply
different
settings (like enabling/disabling checks, mail routing) for
mail
originating from inside - what you configure in policy banks
is
entirely up to you.
The SpamAssassin concepts of trusted_networks /
internal_networks /
msa_networks allow SpamAssassin to recognize which
information in
Received header fields can be relied on, and which not. It
controls
network tests like RBL DUL lookups, SPF, whitelisting based
on received field, etc.
What you configure in mynetworks is not automatically made
available
to SpamAssassin.
It is common that mynetworks is a union of networks listed
in SpamAssassin internal_networks and msa_networks.
