[Dovecot] incorrect dovecot-uidlist?

[Stephan Dietrich]

Hi,
I have some problems with my own mail-client. To fix the problem I want to 
know if my dovecot-uidlist is correct.
Here it is:
cat dovecot-uidlist

I read the documentation on 
http://wiki.dovecot.org/MailboxFormat/Maildir?highlight=(UIDVALIDITY)

Now I see, that the next UID in dovecot-uidlist is here 522 but the last 
UID is 540. So I don't know why the dovecot-uidlist is incorrect.

Thanks for comments...
