stats-writer failed: Permission denied

Hi there!

Since i compile my own dovecot (not using dovecot from debian), i get this error on each startup dovecot with systemd

Feb 07 11:16:35 aldebaran dovecot[7455]: imap: Error: net_connect_unix(/usr/local/var/run/dovecot/stats-writer) failed: Permission denied Feb 07 11:16:35 aldebaran dovecot[7455]: imap: Error: net_connect_unix(/usr/local/var/run/dovecot/stats-writer) failed: Permission denied

I can change the owner and/or permissions of the file, than it works till the next reboot.

How can i set this correctly in my configs?

Some googling didn't give me results for this error.
