Is this correct? thanks, Chas. all smtpd_recipient_restrictions can appear in smtpd_sender_restrictions. Wrong. As SMTP session has MAIL FROM before RCPT TO, you can have sender_restrictions in smtpd_recipient_restrictions, but not vice versa (of course you can, but it'd be useless) - recipient is not known during smtp_sender_restrictions part. by default, smtpd_[client|helo|sender|recipient]_restrictions are executed at RCPT TO time. so it's ok to have a check_recipient_access in smtpd_client_restrictions and so on.

The proper place is in context of what you are trying to accomplish. Ignore the false advice that it must be in smtpd_sender_restrictions. The statement above: all smtpd_recipient_restrictions can appear in smtpd_sender_restrictions. is correct, assuming the default setting of smtpd_delay_reject = yes http://www.postfix.org/postconf.5.html#smtpd_recipient_restrictions Scroll down to the Other restrictions that are valid in this context section. -- Noel Jones
