Recently I've set my iredmail server as primary MX. While test period (as secondary mx) I checked it on http://mxtoolbox.com/ and http://mail-tester.com services - everything gonna be ok.
But as my server become primary it has been got to DNSBL by Spamhaus ZEN. The reason on its site was bad HELO - localhost [127.0.0.1], but all test show it is right fqdn - mail.mydomain.com.
For investigation I've looked into header of my email, here it is (for short view only 'received' fields):
Header of the eml sent with roundcube:

for <xxxxx@gmail.com>; Thu, 19 Feb 2015 09:53:11 +0300 (MSK)First and second 'recieved' are ok , but I need to get rid of unwanted received fields (localhost and some inner IP informations). Looking for some information and get:
Getting rid of 'received':
/etc/postfix/main.cf
header_checks = regexp:/etc/postfix/header_checks
/etc/postfix/header_checks:
/^Received: from .*by mail\.mydomain\.com \(Postfix\) with ESMTPSA/ IGNORE #inner info
/^Received: from .*\[127\.0\.0\.1\].*by mail\.mydomain\.com.*/ IGNORE #all fields by my server containing [127.0.0.1]Turn off adding 'recieved' fields by amavis:
/etc/amavis/conf.d/50-user:
$allowed_added_header_fields{lc('Received')} = 0;Check new header:

for <xxxxx@gmail.com>; Fri, 20 Feb 2015 15:56:28 +0300 (MSK)Still 1 more unwanted recieved 
But how it could be? Check our recieved field:
postmap -q "Received: from localhost (localhost [127.0.0.1]) by mail.mydomain.com (Postfix) with ESMTP " regexp:/etc/postfix/header_checks
IGNORESo i believe this Recieved is added after header_checks. Any idea how to remove it?
My temporary solution to not get in BL is editing
/etc/amavis/conf.d/05-node_id
chomp($localhost_name = `localhost`); #before
chomp($localhost_name = `hostname --fqdn`); #afterThis changes affect to header:
Received: from mail.mydomain.com (localhost [127.0.0.1])
by mail.mydomain.com (Postfix) with ESMTP id 813AE81467
for <xxxxx@gmail.com>; Fri, 20 Feb 2015 15:56:28 +0300 (MSK)Only after this my server stops to get to the Spamhaus BL.
