is this related to mbox only ?
i have no mbox install online to test

did you try install dovecot from scratch with latest sources?

i used a script to install a quick dovecot test server on ubuntu

see
https://sys4.de/de/blog/2013/06/06/postfix-dovecot-ceph-cluster-storage/

beyond

...
Dovecot install
...

then retry with telnet , sorry no time to test myself

I don't know. The bug happens as I explained, and current documentation
says mbox is still supported (I really hope documentation is correct here).

A local virtual machine is more than enough to reproduce this.
It does not need to be online.

Also, it is not required to have client and server on different machines
to reproduce this. They can be the same.

This is dovecot 2.2.16-1 from Debian unstable, released yesterday,
which is the most recent release I can test.
