init.pp: use the postfix default for mydestination

[kenyon]

It is less surprising if the puppet module's default configuration matches a standard default postfix configuration.

[raphink]

I understand the idea, but I'm not really keen on changing defaults. You can easily change that value in hiera with postfix::mydestination in your common data file.

[kenyon]

Why would the module defaults be different from standard Postfix defaults though? That’s a bit weird.

[kenyon]

In this particular case, not having localhost in $mydestination breaks delivery of most system-generated mail going to root@localhost.

Obligatory comment to keep this alive. stale-bot is gross.

I missed this in release 3.0.0 #331 :(

[smortex]

A breaking release was merged to remove Puppet 6 (#351). Let's not miss the opportunity again and merge this!
