[Dovecot] Dovecot + SELinux permission problems

[Johnny]

Hi, 

I have set-up dovecot on a F17 box and am encountering weirdnesses with
SELinux (who isn't??). Again, I am trying to refrain from disabling
SWLinux all together, however tempting, but am stuck in troubleshooting
and hope for some ideas...

With SELinux set to permissive, I can connect to dovecot and log in to
access my mail as expected.

With SELinux enforcing, I can connect to dovecot, but cannot login to
access mail. The log states

,---- log_path = /var/log/dovecot (set in 10-logging.conf)
| Jun 23 15:43:58 imap-login: Info: Login: user=<johndoe>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=15189, secured, session=<xJl+U9PfvgB/AAAB>

| Jun 23 15:43:58 imap(johndoe): Error: Invalid user settings. Refer to server log for more information.

Only thing I can grasp is *write permission* error. ls -l on the
Maildirs shows this should not be the case for uid 1000. 

,---- ls -l
| drwxrwxr-x. 11 user user  4096 Jul  8  2012 Maildir
| \> drwx------. 19 user user  4096 Feb  5 09:04 johndoe

I have no idea what the server log is referring to, in the debug log I get

,---- debug_log_path = /var/log/dovecot_debug (set in 10-logging.conf)
| Jun 23 15:43:58 imap: Debug: Added userdb setting: mail=maildir:~/johndoe
| Jun 23 15:43:58 imap(johndoe): Debug: Effective uid=1000, gid=1000, home=/home/user/data1/Maildir/

`----

I had thought SELinux would log something, but /var/log/audit/audit.log
is blank...

Where to go from here?? Any ideas appreciated...
