dovecot - Dec 2007 - Internal Error - Cannot select inbox

Hi,

I am new to this list although i have been using dovecot for some time
now, i've come accross this error when a user tries to log in

* OK Dovecot ready.
1 login username password
1 OK Logged in.
1 select inbox
1 NO Internal error occurred. Refer to server log for more information.
[2007-12-07 12:51:56]

there are no errors reported in the log files related to that issue for
both dovecot.log and maillog

what i do receive in the log files is

dovecot: Dec 07 12:55:46 Info: imap-login: Login: user=<username at
domain>,
method=PLAIN, rip=::ffff:127.0.0.1, lip=::ffff:127.0.0.1, secured

dovecot: Dec 07 12:55:46 Info: IMAP(username at domain): Disconnected

i can't seem to pinpoint what is going wrong, some things to note

i have existing users who can read email succesfully, its when i create a
new user via postfixadmin, one should note that all directories are
created and owned by vmail whose gid and uid is 500 and for the new users
the directories and mboxes are created succesfully, but even if i copy
over a working inbox of previous user to new user i still get an error so
i don't think it is an mbox formatting issue

another thing is that i can successfully check mail using mutt facility,
even sending using mail clients (outlook express) is possible

other configurations that might be helpful

There really should be an error logged. It just might be in a  
different log file than you expected. See http://wiki.dovecot.org/

Also - this is really old - lots of changes in the released version...

You really should upgrade - or maybe wait until 1.1 goes gold, and then 
upgrade - but do yourself a favor and do it soon.

Hi,
I have read through the dovecot wiki a couple of times, although i alwasy
get errors issuing the give dovecot --log-error command, as in the option
is not available... but i have st my log_path to dovecot.log and info_path
to dovecot.info and still no errors are reported to dovecot.log in my
syslog configuration all mail messages go to maillog and also no error
messages are shown in there,,, where does dovecot log these errors

upgrading dovecot for me is to be treated as last resort since this is a
production server, and i have a few backup options, i need a solution that
is reversable if the need arises...

i'm using dovecot 1.0.rc15 the one that comes with RHE5

Hi,

through various trial and errors i've found the solution to my problem, i
disabled the mbox_min_index_size, it was set to 200 ( i think i read in
some  tutorial that this will increase performance)

#mbox_min_index_size = 200

After disabling it the errors stopped though i still have a niggling issue
still unresolved

Where do the error messages go ??? i read through the debuging tutorial,,
the dovecot --log-error command doesn't work,,, or maybe i am not
executing it properly

# dovecot --log-error
Usage: dovecot [-F] [-c <config file>] [-p] [-n] [-a]
       [--exec-mail <protocol>] [--version] [--build-options]
Fatal: Unknown argument: --log-error

That is what i get after command execution, how do i find out where the
error messages are logged ???
