dovecot - Mar 2012 - 2.1: Error: Maildir filename has wrong S value, renamed the file from

Hi!

Starting with 2.1.1 we suddely encounter quite a lot of these messages:

Mar  2 11:09:28 postamt dovecot: imap(username): Error: Maildir filename has
wrong S value, renamed the file from

While this has (assumedly) been working with 2.0.18. Another issue
with this: This fixes ONE file, and throws an error. Repeatedly
accessing this folder fixes more files, until at some point all files
were fixed.

Hello, same problem here after upgrading from 2.0.18 to 2.1.0, 
apparently it happens only on servers with qmail, not on servers with 
exim or dovecot as lda:

Dovecot v2.0 didn't detect these problems, and might have truncated some
mails in some situations.

Right, because after it notices a problem it disconnects the client since it
can't really do anything else. Running doveadm fetch for all the mails
should fix all of them.

Alternatively you can just tell Dovecot not to care about it:
maildir_broken_filename_sizes=yes. Although you probably can't do that if
you have compressed mails.
