Yes, although I would suggest something like this:

action_add_header('X-Debug-Msg', "Deleting recipient $recip");

Remember when using this trick that messages other than the ones you are
sending as tests might get these headers inserted.  I like to use X headers
like 'X-Debug-Msg' in order to play nice with other MTA's that my message
might pass through.  They should ignore any X header that they don't
recognize, but a header like "Deleting recipient:" might cause issues.

You can still do all of the normal MD checks (including virus checks) while
skipping just the SpamAssassin scan.  That's what I do...

No problem...
