You can use it to save a timestamp to a database.

How may I disable message deletions via IMAP for some or all of my users?

And while it says "expunge", it really means delete and expunge.

I would be fantastic if dovecot could release arm64 debian packages to

Thanks for your reply.
I'm now very confused. Looking at
https://github.com/dovecot/docker/blob/main/2.3.21/Dockerfile this
container clearly just installs the debian package from the community repo.
That's why I thought publishing a arm64 debian package would enable a
arm64 docker image.

No, that client is using the programming method to access us.
