Hi everybody,

I run two redundant Dovecot servers with a shared Maildir on a GlusterFS volume and a SQL authentication backend based on a mirrored MariaDB database.

Because of the splitbrain situation I would like to add two Dovecot Director as proxies. 

Can someone explain me how to solve this problem?

### Proxy Config ###

passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql }

passdb { driver = pam }
