Hi list

I have weird issue with my Dovecot (476cd46418)

(Evolution) all over sudden dovecot starts to panic

The only way that I found to get around is to unsubscribe the INBOX
folder and subscribe again. Then the error is gone until I delete a
bunch of messages again.
The error only occurs if I delete the messages within short time or

delete as many as I want.

Cheers and have a good one
