3. Hack qmail-smtpd such that it does what rblsmtpd does only when clients issue a MAIL FROM command, and only if they haven't already authenticated. (I seem to vaguely recall that someone wrote a patch to do this, but I can't vouch for the quality of such patches... in my personal opinion, this is a bad solution.)

Tell one reason why this feature is a bad solution.

1. It requires mucking with qmail-smtpd.c unnecessarily.
2. It requires qmail-smtpd to rely on a resolver library.
3. Blacklists must either be hardcoded, or require command-line
   options (which requires more complex command-line parsing, which
   will require hand-tuning to work well with your SMTP-AUTH patch),
   or defined in yet-another-control-file.
4. I don't like it.

Though, truth be told, #4 is sufficient for me, and I reserve the right to dispense recommendations based solely on #4.
