When trying to sent a mail to [email protected] postfix will complain warning: Illegal address syntax from host in RCPT command: <[email protected]>
and reject the message with "501 5.1.3 Bad recipient address syntax". Now can anyone point me to the part in the RFC that prohibits the "-" at the start of the local part? Because this limitation only exists for domain parts afaik. [email protected] should be OK! [email protected] should NOT!
