I am currently facing the following log output:

Apr 26 16:40:28 h2290750 dovecot: auth: Error: pgsql(localhost): Connect failed to database mail: could not connect to server: Permission denied Apr 26 16:40:28 h2290750 dovecot: auth: Error: #011Is the server running on host "localhost" (::1) and accepting Apr 26 16:40:28 h2290750 dovecot: auth: Error: #011TCP/IP connections on port 5432?

I have double checked the database. It is listening correctly and I can connect to it via

psql -U mailreader mail

I provided all necessary information to dovecot via this configuration snippet:

driver = pgsql connect = host=localhost dbname=mail user=mailreader password=secret default_pass_scheme = SHA512

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.

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

TYPE DATABASE USER ADDRESS METHOD

Mail stuff

host mail mailreader 127.0.0.1/32 md5 host mail mailreader ::1/128 md5 local all all md5 host all all 127.0.0.1/32 ident host all all ::1/128 ident

What about the "Does Postgres logs something?"

...

Do you have SELinux or something like that running?

What about this question?

...

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.

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