Today, we launch dovecot in the background and chasquid in the
foreground using sudo.
This means that dovecot failures won't propagate, and signals to the
container (e.g. to stop it) also don't get propagated to dovecot
(because it's in the background) or chasquid (because they don't go
beyond the sudo process).
Thanks to [Guiorgy@github](https://github.com/Guiorgy) for identifying
the problem, proposing alternatives, help debugging, and discussing this
in https://github.com/albertito/chasquid/pull/70.
