All the %*_by_ccat settings base their result on a current
highest contents category (sorted by major first, then minor).
If a custom hook can turn on a suitable ccat soon enough,
the rest of the program will comply.

Sounds good. Check the attributes is_mlist, is_bulk and is_auto
(in package Amavis::In::Message). The is_mlist is true if a mail
is coming from a mailing list.

Ok.  The @spam_subject_bulk_maps is not necessary, you can add
a listref directly into %subject_tag_maps_by_ccat if you prefer.

The %subject_tag_maps_by_ccat can be adjusted in a config file,
but flagging a "CC_SPAMMY,2" would need to be in a custom hook.

Should be handled correctly by existing code.
