I have this case that postfix produces this header in receiving mail :
Received: from mcpmr014msb.fastweb.it (Received: from mr014msb.fastweb.it (mr014msb.fastweb.it [85.18.95.103])
)
(using TLSv1.3 with cipher TLS_AES_256_GCM_SHA384 (256/256 bits))
(no client certificate requested)
by EFABACKUP.gruppocomet.it (MailScanner Milter) with SMTP id 4Hkp3D1Z60z3sN7lb
for nicola.piazzi@gruppocomet.it; Wed, 3 Nov 2021 14:46:48 +0100 (CET)
This is a maillog extract :
Nov 3 14:46:47 EFABACKUP postfix/smtpd[2634]: connect from mr014msb.fastweb.it[85.18.95.103]
Nov 3 14:46:48 EFABACKUP postfix/smtpd[2634]: Anonymous TLS connection established from mr014msb.fastweb.it[85.18.95.103]: TLSv1.3 with cipher TLS_AES_256_GCM_SHA384 (256/256 bits) key-exchange X25519 server-signature RSA-PSS (2048 bits) server-digest SHA256
Nov 3 14:46:49 EFABACKUP postfix/cleanup[3710]: 4Hkp3D1Z60z3sN7lb: milter-discard: END-OF-MESSAGE from mr014msb.fastweb.it[85.18.95.103]: milter triggers DISCARD action; from=a.bisio@agenziachiesta.com to=nicola.piazzi@gruppocomet.it proto=ESMTP helo=<mcpmr014msb.fastweb.it>
It seems that host that connect mr014msb.fastweb.it[85.18.95.103] differs from helo name mcpmr014msb.fastweb.it and halo name have an entry in dns
So postfix produces a long amail with a ) that goes in a new line and then outlook became unreadable for this message
Header newline if helo differs

Re: Header newline if helo differs
It will roll into v4 soon, just need to budget some time to get it pushed out. In the meantime, you are welcome to make the required change to /usr/sbin/MSMilter. The next update will will make it permanent.

Re: Header newline if helo differs
line changed works perfectly
but i think that the problem was the provier that send an helo tht differs from hostname

Re: Header newline if helo differs
It is, but we shouldn't add two Received: headers regardless of the mismatch.
