Right. Thanks for tracking it down. On startup the log
should report:

  amavis[46211]: ANTI-VIRUS code      NOT loaded
  amavis[46211]: ANTI-SPAM code       NOT loaded
  amavis[46211]: ANTI-SPAM-SA code    NOT loaded
  amavis[46211]: Unpackers code       NOT loaded

Consider also:

  $bypass_decode_parts = 1;

which turns off also the first-step MIME decoding.

And if only SQL logging is needed (for other server's
penpals benefit),
the penpals checks by a dummy amavisd can also be turned
off:

  $penpals_bonus_score = 0;

The value of $remove_existing_spam_headers is irrelevant if
anti-spam code
is not loaded, existing X-Spam* headers are not stripped if
replacements
are not intended to be provided.

Unnecessarily complicated, the local_domains_maps=()
suffices.

It might matter if they use SPF, or if you are DKIM-signing
their
outbound mail for them.

So you _are_ in position to get hold of such traffic, why
not just
re-route it to wherever you like.
