Hi, the following SMTP sessions works:
---------------------------------------------- > telnet localhost 25 ... EHLO localhost ... MAIL FROM: root 250 2.1.0 Ok RCPT TO: root 250 2.1.5 Ok DATA 354 End data with <CR><LF>.<CR><LF> To: root From: root Subject: test . 250 2.0.0 Ok: queued as 1FE944A4078 ---------------------------------------------- I receive the email in the correct mailbox. My main.cf contains append_at_myorigin = yes append_dot_mydomain = yes local_header_rewrite_clients = In the received mail the From: and To: headers are indeed only "root" (and not "[EMAIL PROTECTED]"). But what makes postfix accept the non-fully-qualified envelope sender and recipient addresses? I don't want to allow this, I want to enforce "MAIL FROM: [EMAIL PROTECTED]" etc... Thanks and regards -stefan-
