dovecot - Oct 2011 - I'm the ONLY user that can get mail

Hi,



I'm stumped.  I can access the postfix server to read my mail.



BUT I'm the only user that can.



Everyone else get rejected.



Here's the syslog entry for another user:

...dovecot: pop3-login: Disconnected (auth failed, 1 attempts): 
user=<jmarino>, method=PLAIN, rip=192.168.0.51, lip=192.168.0.189



And here's an entry for me:

...dovecot: pop3-login: Login: user=<ed>, method=PLAIN, rip=192.168.0.51,
lip=192.168.0.189



So ONLY I am able to get my mail.  And this is consistent.



The other users and passwords are valid.  I've re-set them just to be sure.



I suspect it's a rights issue but I've checked the rights for all 
/var/mail files and they're all the same except the owner of the file is
 the actual owner.



I also checked all the rights for the files in /etc/dovecot.  They all 
look OK and they all have root/root for the owner and user.



Since I installed the system and did all the editing of the 
configuration files it's possible, but unlikely, that I'm the owner or 
group of some key file.  I've looked for that but found nothing 
suspicious.



Is it possible I may have given myself root access?  I don't see how.  
My UID is 1000. Does the fact I'm the first user (per my UID) make a 
difference?  I would think not.



So I'm stumped.  I don't have a clue as to where to look or what to do
next.



Any thoughts will be greatly appreciated.



This is Dovecot 1.2.15 on Ubuntu 11.04.  A new/clean install.

Plaintext passwords are allowed.

Here's dovecot -n 
# 1.2.15: /etc/dovecot/dovecot.conf
# OS: Linux 2.6.38-11-generic i686 Ubuntu 11.04
protocols: pop3
disable_plaintext_auth: no
login_dir: /var/run/dovecot/login
login_executable: /usr/lib/dovecot/pop3-login
mail_privileged_group: mail
mbox_write_locks: fcntl dotlock
mail_executable: /usr/lib/dovecot/pop3
mail_plugin_dir: /usr/lib/dovecot/modules/pop3
auth default:
  passdb:
    driver: passwd
  passdb:
    driver: passwd-file
    args: /etc/passwd.dovecot
  userdb:
    driver: passwd





Thanks

So youre sure the mail isn't being delivered to the users maildir? but 
you just can't access it with IMAP.
You can test authentication if using saslauthd by typing 'sudo 
testsaslauthd -u username -p password -s smtp'. Just some thoughts.
