You'll have to back up that claim with: # postfix reload ... submission of a new message via TCP port 25 ... ... logs showing that message entering and leaving the queue ... ... unmangled (verbatim whitespace and newlines) output of: $ postconf -nf $ postconf -Mf When a content_filter is set for smtpd(8), it is used.
