Wael MANAI: > Yes I know that. Look this is the mailer-daemon sent by postfix (bold > line at the end of the message). In the notification only "552 > Requested ..." must appear, why 250-PIPELINING too?
By the multiline rule of RFC 5321:
1) The EHLO reply is:
250 whatever
2) The MAIL FROM reply is
250-PIPELINING
552 whatever
Of course, this is malformed SMTP. Postfix reports the entire
response instead of trying to "fix" malformed SMTP.
