Ok, thanks for applying the clue stick so gently... ;) I thought that since the check was under smtpd_recipient_restrictions that all of those checks would be applied before the recipient was 'validated'... apparently that assumption was incorrect and the source of my problem... So, would moving the check above 'reject_unauth_destination' fix this? Or is there some other way to force postfix to perform all of these checks before validating a recipient? -- Best regards, Charles
