Peter,

Yes, I believe it should work.
Make sure the recipient is local - @local_domains_maps must be configured correctly.

Do you get X-Spam-* header fields inserted? If yes, the @local_domains_maps is probably correct. If no, then Subject is not modified for the same reason as X-Spam-* headers are not inserted: recipient not considered local.

It is more usual that ' ****SPAM**** 'is inserted at tag2 level (=spammy), and not at kill level (whose primary purpose is to block mail in most cases). The above can be simplified to a single:

  $sa_spam_subject_tag = ' ****SPAM**** ';

and leaving out the assignment to %subject_tag_maps_by_ccat, the default usually suffices, also other values are the same as defaukt, so need not be reasserted again (see amavisd.conf-default).

The sample-spam-GTUBE-junk.txt test message contains a GTUBE test pattern, which should score very highly by SA, see http://spamassassin.apache.org/gtube/
