We just upgraded to ZCS 5.0.4.
While we expected our Postfix main.cf tweaks under 4.5.11 to have disappeared during the upgrade, it seems the previous method of using "postconf -e <variable>=<value>" followed a "postfix restart" doesn't survive a server restart.
We see there are a lot of new Postfix variables set in localconfig.xml.
Is editing localconfig.xml now the correct way to make permanent tweaks to Postfix?
We'd like to set the following:
<value>[Server Public IP Address]</value>
(The first three together we find to be an effective anti-UCE technique.)
We are not finding anything in the Administrators Manual or the Support Portal about this.
