For prior art, see message_drop_headers, which specifies headers
that are to be removed.
message_drop_headers (default: bcc, content-length, resent-bcc, return-path)
Names of message headers that the cleanup(8) daemon will
remove after applying header_checks(5) and before invoking
Milter applications. The default setting is compatible with
Postfix < 3.0.
Adding message_sender_headers and message_recipient_headers may
make sense, i.e, one main.cf parameter per HDR_OPT_MUMBLE flag.
