dovecot - Mar 2006 - FreeBSD 5.4/Dovecot 1.0.b3: lots of error messages

Hi!

I installed Dovecot from the FreeBSD port. I have about 20 users on this 
machine and used popper before switching.

I get a lot of error messages like:

dovecot: Mar 21 10:03:41 Error: pop3(xxx): mbox sync: UID 
inserted in the middle of mailbox /var/mail/xxx (37326 > 35874, seq=1,
idx_msgs=26)

dovecot: Mar 21 10:06:17 Error: imap(yyy): mbox sync: UID 
inserted in the middle of mailbox /var/mail/yyy (37352 > 36945, seq=1, 
idx_msgs=2)

dovecot: Mar 21 10:06:18 Error: imap(yyy): kevent(1) in 
io_loop_handle_add() failed: Bad file descriptor

dovecot: Mar 21 10:06:18 Error: imap(yyy): kevent(1) in 
io_loop_handle_remove failed: Bad file descriptor

dovecot: Mar 21 10:06:22 Error: imap(yyy): mbox sync: UID 
inserted in the middle of mailbox /var/mail/yyy (37354 > 36945, seq=1, 
idx_msgs=205)

Most of the errors are the mbox sync messages. The users report that they 
get all mails double, triple and more... I think this is connected to the 
UID problem.

My config file looks like that:

protocols = imap imaps pop3
disable_plaintext_auth = no
log_path =  /var/log/dovecot.err
info_log_path = /var/log/dovecot.info
log_timestamp = "%b %d %H:%M:%S "
login_process_size = 64
verbose_proctitle = yes
first_valid_gid = 0
mail_extra_groups = mail
default_mail_env = mbox:/var/mail/%u
protocol imap {
   imap_client_workarounds = delay-newmail outlook-idle netscape-eoh 
tb-extra-mailbox-sep
}

protocol pop3 {
   login_executable = /usr/local/libexec/dovecot/pop3-login
   mail_executable = /usr/local/libexec/dovecot/pop3
   pop3_uidl_format = %08Xu%08Xv
   pop3_client_workarounds = outlook-no-nuls oe-ns-eoh
}

auth default {
   mechanisms = plain
   passdb pam {
   }
   userdb passwd {
   }
   user = root
}
plugin {
}


Any ideas?

These mean that X-UID header in the mbox file don't match what Dovecot
was expecting to see based on its indexes. This shouldn't be happening
unless the mboxes keep changing in very unexpected ways, for example if
the mails are rearranged inside the file or if eg. older version of the
mbox is restored from backups, or something similar.

Is anything else than Dovecot touching those mbox files?

I've fixed a couple of these since beta3. They don't cause any problems
though.
