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 directory:

dovecot: 2008-06-23 15:09:46 Error: IMAP(marek.chajecki): Invalid data in file /var/mail/Maildir/marek.chajecki/.Sent/dovecot-uidlist

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.

Config:

root@warsaw Maildir # dovecot -n # 1.0.13: /etc/dovecot/dovecot.conf log_path: /var/log/dovecot.log info_log_path: /var/log/dovecot.log log_timestamp: %Y-%m-%d %H:%M:%S ssl_listen: * login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login login_process_per_connection: no login_processes_count: 15 login_max_processes_count: 512 max_mail_processes: 4096 mail_privileged_group: mail mail_location: maildir:/var/mail/Maildir/%u maildir_copy_with_hardlinks: yes auth default: worker_max_count: 100 passdb: driver: pam args: cache_key=%u dovecot userdb: driver: passwd

Any help will be appreciated!
