Oh - there are quiet more possibilities and the syntax slightly has 
changed.

The problem is to understand the dependencies.

Then the old configuration should work.
But it does not.

Now i have found the solution.
It seems to help to ask you. ;)

The solution was to change from
listen = [::]
to
listen = *, [::]

There is no explanation for it - just try and error ...

The output seems only to be the configuration that was read.


I lost many hours just to find out that i have to define e.g.
service imap-login {
Before there was no error, dovecot running and no ports listening.
Sorry - that's foolish.

Seems only onetime.
So no problem.

The client should left the message on the server with no local copy.
