DKIM verification in amavisd as well as in SpamAssassin is
independent from trusted_networks / internal_networks / msa_networks,
i.e. works the same regardless of mail flow direction and its source.

Yes it does (regardless of version). Signing is done last, just before
the mail message is being fed back to an MTA. So the signature
that is yet to be generated is not seen by SpamAssassin and
a DKIM_ADSP_* rule could hit.

What is strange here is that the message does contain a:

  Authentication-Results: (amavisd-new);

which apparently means that a signature by was already
present at the time of signature verification, so SpamAssassin
should have seen it as well.

Perhaps a domain in a From header field did not match exactly
the signing domain of a signature? Maybe it was its subdomain.
