You want to verify rcpt id for @abc.mydomain.com and not for @mydomain.com That should be easy put in main.cf ---------------------- smtpd_recipient_restrictions= check_recipient_access hash:/etc/postfix/validusers, ... ... ------------------------ in this file --------------------------- [EMAIL PROTECTED] OK [EMAIL PROTECTED] OK ... ... abc.mydomain.com REJECT User not found mydomain.com DUNNO ------------------------ But I would suggest you verify users of "mydomain.com" too. Accepting undeliverable mails is usually a very bad idea
