## What does this PR do?

If the [mailu setup utility](https://setup.mailu.io/master/) is used with the Compose flavor, in step 4 a list of public host names needs to be provided:

The [first entry in this list is configured as hostname by postfix](ddac2672fc/core/postfix/conf/main.cf (L10)). That is crucial: if the reverse DNS entry for that host is not the same as this first entry in this list, it will be a mismatch between rDNS and HELO, which will lead to bad scoring in many spam filters.

This commit clarifies that point.
It also fixes a missing parenthesis.
