That's expected, Postfix will accept one *or more* CRs before LF as CRLF. https://github.com/vdukhovni/postfix/blob/d2d9daf4d1b5e8cec47bd7434264f92b4fe1ba30/postfix/src/global/smtp_stream.c#L437-L438 Does that also need to be more strict? :-( -- Viktor. _______________________________________________ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org
