Content of Received:- and Message-Id:-Header created by CSSMTP should be customisable

Each Mail processed by CSSMTP a SMTP Received:- and a Message-Id:-Header is attached by CSSMTP. These headers are visible for every node in the transmission path and for the Mail receiver also.

Both headers contain security sensible information of the sending zOS system like DNS Domain Names, NJE Node Names, Mail creating Job-Names and their associated RACF Userid (if Parameter USERINFO YES is coded), Name of CSSMTPs Start-Procedure, type and version of the operating system. Most of those fields are not needed to transmit the mail to its target and are not needed to know outside the data center:

Received:-Header with parameter "USERINFO YES"
njenodename.domainname (njenodename) by dnsname.domainname (systemname )
for <RACFuserid@njenodename> with ESMTP (IBM stcname z/OS V02R01.00) Id
jobname.jobnumber.dnsname@domainname.date.time ; date time timezone

Received:-Header with parameter "USERINFO NO"
njenodename.domainname (njenodename) by dnsname.domainname (systemname )
for <stcname@njenodename> with ESMTP (IBM stcname z/OS V02R01.00) Id
dnsname@domainname.date.time ; date time timezone

Message-Id:-Header
dnsname@domainname.date.time

The content of both headers should be made customisable.
