IMAP Folder Mail Separator

[Alex]

Hi,

Perhaps I'm just not understanding, but I've spent the last few days
reading through those links, and I just don't understand. I'm really
hoping my doveconf output will help. I've also understand this may be
a long-standing thunderbird bug, but it worked up until a few months
ago after a dovecot/fedora upgrade.

Please let me know what other information I can provide to help
troubleshoot this.
