Dovecot, Thunderbird and messages in wrong folder

Hello,

Sometimes it happens that messages (e.g. one or two) appear in wrong 
folders in Thunderbird (latest version, also past versions, different 
computers, also Earlybird). When I repair the folder 
(folder/Settings/Repair Folder) in Thunderbird, the folder is correct then.

It happens on my new server with Fedora 20, Dovecot 2.2.13 and Maildir 
but it also happened on my old server with Fedora 1, Dovecot 2.2.13 and 
mbox.

Has anyone the same issue?
Any guess whether it might be a thunderbird or dovecot issue?
Anyone has the same issues with thunderbird and a different IMAP server 
(e.g. cyrus)?

Thank you.

Ciao,
Gerhard
