I'm running dovecot 2.3.19.1 on debian stable. I just started seeing a slew of these in my log:

I realize this is a slightly old version of dovecot but this is what's in debian's stable package repository. I see 2.3.21+dfsg1-2 in testing and 2.3.21+dfsg1-3 in unstable. I really try to avoid installing this on production.
I didn't recently change anything in my configs on the server. I did start recently using 'eM Client' on Windows a couple days ago, could that have caused this? Mail seems to continue to come in to my imap clients, but these errors in the log are worrying!

Would you be open to using https://repo.dovecot.org in your production? These are debian-compatible packages.
