Hi! Any chance you could collect coredumps for these and posting output of gdb /usr/lib/dovecot/imap /path/to/core bt full systemd-coredump can be used for this, and https://www.dovecot.org/bugreport-mail contains hints how to get core dumps otherwise.

I wonder if you could get a coredump for the "message-part-data.c" panic too? Additionally it would be interesting to see the mail from INBOX of user1 at email.com (UID=3454), that makes it crash. You could use one of the obsfuscate tools from https://www.dovecot.org/tools/ to provide . The crash that occurred in imap-bodystructure.c is fixed in coming releases.
