Do the actual greylist checking in the RCPT acl, but instead of
deferring on it, set an acl_mN variable.  In the predata, defer based on
that variable.

Note that if _any_ of the recipients results in an accept, you should
accept all recipients -- greylisting is designed to verify that the
sender is a real MTA, not a spammer's zombie host, so as long as that's
been proven for any single sender, there's no point in further greylisting.
