Dovecot is not restarted if service dies #731
Description
on VPS with low RAM (ex. mine with 4GB) eventually filtermail and opendkim can use a lot of RAM, I suspect this was the reason Dovecot service got killed/died, in any case, this caused hours of downtime because it coincidentally happened while I was sleeping, if dovecot service would be configured to auto-restart, like filtermail service is, there would have been little downtime, since after filtermail got also killed and restarted the memory usage went down again
TL;DR: please set:
Restart=always
RestartSec=30
for dovecot service same way as it is done for filtermail service so if service dies unexpectedly the server can recover without big downtimes until admin notice or is available
