Hello,

I'm using Thunderbird 102 to atempt to retrieve my messages via imap (have tried both 143 and 993) first I wasn't getting any error messages now I am. This is with Dovecot 2.3 on Debian 12.5. Here's the error messages. I do not believe the first set related to public mailboxes is related but I'm not sure what it's problem is either, the problem seems to be corrupted cache.
