Copied it into Applications and purged out the application data and it seems fine now - thanks!
It is a self-hosted install, using default dovecot on Alpine 3.14 in docker, which looks to be 2.3.15-r0. I've not had any issues with other mail clients. It appears to be that ID line which is causing the error, but nothing helpful is being captured in Dovecot sadly. SMTP works fine.
