Nope.

Yup.  You could wrap it in a delete_all_recipients() function if you like.

Nope.  Anything you do in your filter that only affects memory within
the Perl process has absolutely no effect on Sendmail.  You have to
call one of the functions that communicates with Sendmail to actually
affect anything.

If you look at the source, you'll see that delete_recipient and
add_recipient make notes in the RESULTS file that ask the C code to
call appropriate milter functions to *actually* make the changes.
