I set the host to 127.0.0.1 now. And my pg_hba.conf looks like that:

[snipp]

The folder /var/run/postgresql is not existing on my machine.

The problem is still present. :(

What's the output of

root # lsof -np $( pgrep -fl bin/postgres|awk '{print $1}' )
root # netstat -tlnp|egrep postgres

does Postgres allow connections on "host ::1" for user mailreader ?
Actually I wonder, because I thought the Postgres lib defaults to
"local" (socket) by default on localhost -> does Postgres allow
connections on "local" for mailreader? Permissions are configured in
pg_hba.conf, but -> Does Postgres logs something? It should if PG
denies the connection.

Do you have SELinux or something like that running?

I remember that I had a server that had wrong permissions on:

ls -al /var/run/postgresql

drwxrwsr-x  2 postgres postgres 4096 Feb 10 07:32 ./
srwxrwxrwx  1 postgres postgres    0 Apr 26 23:15 .s.PGSQL.5432=

the .s.PGSQL. socket is the local socket usually used for localhost
connections and automatically found by libpg.
