I renamed the "sent_mail" folder to "sent_mail_test" (using
Thunderbird). This action removed all UIDs in the filesystem inside the
sent_folder, which were not known by cyrus.* databases in the
"sent_mail" folder. Afterwards I renamed the folder back to "sent_mail".
The only UID which wasn't deleted is UID 1., which is correct, because
this UID was created inside the sent_mail after the users
copy/movement/whatever session, first new email/UID. A following
chk_cyrus didn't come up with errors. :)

Checking files:

# ls -li /var/spool/cyrus/mail/u/user/userxyz/sent_mail/1766. 
No such file or directory 
-> good, deleted by my renaming 

#ls -li /var/spool/cyrus/mail/u/user/userxyz/Gesendete\ Elemente/1807. 
10897103 -rw------- 3 cyrus mail 5520 Sep  9
23:08 /var/spool/cyrus/mail/u/user/userxyz/Gesendete Elemente/1807.
-> good, still there

# ls
-li /var/spool/cyrus/mail/u/DELETED/user/userxyz/sent_mail/54101FA9/1766.
10897103 -rw------- 3 cyrus mail 5520 Sep  9
23:08 /var/spool/cyrus/mail/u/DELETED/user/userxyz/sent_mail/54101FA9/1766.
-> good, will be hopefully deleted after 7 days be nightly expunge

Question still is what caused this inconsistence between cyrus.*
databases and fileystem, how can that happen?

Cheers
