[Dovecot] Maildir and Invalid data in file

Hi Timo,

Regarding our conversation in IRC, I'm attaching the uidlist and copying in the original 
message just in case.

I'm using dovecot version 1.0.13 on reiserfs on hardware RAID-0, but I'm getting the
following error in the logs every time one user tries to access his old mails in the .Sent

dovecot: 2008-06-23 15:09:46 Error: IMAP(marek.chajecki): Invalid data in file

As a result he fails to get access to the emails in this folder.

I've googled a bit and read that deleting the uidlist makes dovecot recreate it, but after
some time the same thing happens. It's a new hard drive, so I don't think this is a hard
drive fault.

Some additional info: this server is being used by about 200 users who get about 100
emails daily each one of them.

Any help will be appreciated!
