Hello,

Is it possible to configure SQL connection keepalive for Dovecot?

Probably what I have to do is "Note that the SQL backend must be used via Proxy", however I was unsucsessful in figuring out how can I setup this to get use of connection pool at Dovecot.

Thanks.

$ dovecot --version 2.3.20 (80a5ac675d)
