Would you consider adding a few lines of code to include the
HELO host in the set of environment variables passed to the
rcptfilter/smtpfilter scripts?

I've found that a high percentage of spam email
seems to use one of a small number of obviously-bogus
HELO names - either my system's numeric IP address, or "friend",
or "localhost". I'd like to track and reject these via the
rcptfilter, if they get past the other (SPF and DNSBL) tests.
