My guess is that this is a kubernetes specific issue and not a dovecot
issue.
Please provide kubernetes logs. Also: how is your storage implemented?
Any chance more than one dovecot instance are accessing that storage? Is
the storage available on the node where the container runs?

Just for completeness sake I will throw some in:

*) https://lib.rs/crates/dkim-milter
*) https://github.com/fastmail/authentication_milter
I have not yet had time to look at them, so no comment on their usability.
