I have an /etc/postfix/recipient_access file that looks like this: babcom.com 554 Bad spammer! You didn't use the MX record! @babcom.com 554 Bad spammer! You didn't use the MX record! a...@caerllewys.net 554 This user does not accept mail a...@caerllewys.net 554 This user does not accept mail b...@caerllewys.net 554 This user does not accept mail dae...@caerllewys.net 554 This user does not accept mail ... However, although I know I *USED* to use this to deny mail to system users, there is no longer any configuration rule in my main.cf to invoke it, and I don't remember what it was. I'm guessing I used to have it in smtpd_recipient_restrictions. Why it's no longer there, I have no idea. Perhaps at some point I simply *accidentally deleted* the rule.
