this looks like "dovecot" host is not resolvable.
Yes, that's exactly what happens in many container based setups when
a container is not running anymore - it's DNS name get's retracted.
DNS entries are handled by the container engine and dynamically added
and removed to allow inter-container communication. Postfix even got
some code to handle some DNS related error conditions like that in 3.7.1.
