How to control the header cyrus lmtp adds to an e-mail upon delivery

[Michael Hieb]

Does anyone know how to control the header cyrus lmtp adds to an e-mail 
upon delivery?

I see following added to headers of e-mail received via cyrus lmtp from 
postfix

Received: from mail.domain1.net (mail.domain1.net [192.168.1.75]) by 
MAILSERVER (Cyrus v2.4.18) with LMTPA; Fri, 26 May 2017 00:26:03 +0000

I would like to  change "MAILSERVER (Cyrus v2.4.18) with LMTPA" to show 
FQDN "imap.domain1.com (Cyrus v2.4.18) with LMTPA".



Configuration as follows:

Here is my configuration in /etc/cyrus.com

     # at least one LMTP is required for delivery
     lmtpdomain1               cmd="lmtpd -a" 
listen="mail.domain1.com:lmtp" maxchild=-1 maxforkrate=100

I have servename set in /etc/imapd.conf (and this does appear correctly 
in the banner when a client connects to imap - I realize this is 
independent from lmtp)

     servername: imap.domain1.com

Here is the delivery in /etc/postfix/main.cf

     relay_transport = lmtp:mail.celoso.net:2003




Let me know what other information you require.

Appreciate any clue or advice.
