So, the question is.... How much ram should dbmail imapd allocate

Should I arrange some kind of automatic restart at night?
Dbmail 3.1.12
The amount of allocated memory should be pretty stable. If you see
increasing amounts, chances are you hit a leak. Since you run 3.1.12, I
would call that a certainty. Upgrade to 3.1.13 since that fixed a
significant leak.

In general, it is advisable to put an imap proxy in front of dbmail.
Nginx and Dovecot are known to provide better networking behavior under
adverse conditions, i.e. mis-behaving tcp connections. Dbmail has been
getting better at those, but better be safe than sorry.
And yes, a restart every night is cheap and fast. No reason not to do
it. If that is in conflict with your HA policy, put a HA-Proxy instance
in front, and do rolling restarts.
