It *should* (I have a system doing this, although I've left the spam
threshold at its default);  but depending on the fine details of your
complete setup (OS, install method, current config, etc, etc, etc...) it
MAY require sa-mimedefang.cf from somewhere.  (This changed recently,
but AFAICT it didn't affect the system I have calling SA from MD.)  Note
that some settings (those that control what headers SA adds to the
message) do NOT do anything in MD - you have to do that in your
mimedefang-filter.

Yep.  In filter_end() add a line like:
action_add_header ("X-AVScan","Clean");
(or whatever).  I think you can do this earlier as well;  check the
manpage.

In the default mimedefang-filter, in filter_end(), you should see some
code relating to SA.  You can use action_add_header() and
action_change_header() to add or change any headers you like.

Check the man page for mimedefang-filter for details on all of the
functions you can use and where you can use them.
