He should, if he had an authenticated SMTP session. But he doesn't.RBL checking is done BEFORE he connects to qmail-smtpd. If he's blacklisted, he gets dropped BEFORE he qmail-smtpd gets a chance to ask for his userid/password, and the authentication is never done. He has no authenticated session. Another good case for a separate relay server on port 587, which only accepts mail from authenticated users, and has no RBL blocking in front of it. |
