dovecot - Feb 2008 - auth default : passwd-file Can't open file: Permission denied

Hello,

I'm attempting to migrate from an existing dovecot .99 install to dovecot
1.0.rc15 on a fresh up to date CentOs 5.1.  I'm not sure what's causing
this
permissions error on startup - I've tried 777,644, and 600 chmods but
it's
always this same error:

Feb  1 12:43:05 ns2 dovecot: Dovecot v1.0.rc15 starting up
Feb  1 12:43:06 ns2 dovecot: Auth process died too early - shutting down
Feb  1 12:43:06 ns2 dovecot: auth(default): passwd-file
/var/spool/virtual/passwd: Can't open file: Permission denied
Feb  1 12:43:06 ns2 dovecot: child 16411 (auth) returned error 89
Feb  1 12:43:06 ns2 dovecot: Temporary failure in creating login processes,
slowing down for now

Here's some more information from the shell:

# dovecot -n
# /etc/dovecot.conf
login_dir: /var/run/dovecot/login
login_executable(default): /usr/libexec/dovecot/imap-login
login_executable(imap): /usr/libexec/dovecot/imap-login
login_executable(pop3): /usr/libexec/dovecot/pop3-login
login_user: vmail
mail_location: maildir:/var/spool/virtual/%d/%n
mail_executable(default): /usr/libexec/dovecot/imap
mail_executable(imap): /usr/libexec/dovecot/imap
mail_executable(pop3): /usr/libexec/dovecot/pop3
mail_plugin_dir(default): /usr/lib/dovecot/imap
mail_plugin_dir(imap): /usr/lib/dovecot/imap
mail_plugin_dir(pop3): /usr/lib/dovecot/pop3
auth default:
  mechanisms: plain login
  verbose: yes
  debug: yes
  passdb:
    driver: passwd-file
    args: /var/spool/virtual/passwd
  userdb:
    driver: static
    args: uid=vmail gid=vmail home=/var/spool/virtual/%d/%n



# ls -l /var/spool/virtual/passwd
-rw------- 1 vmail vmail 37639 Jan 31 14:27 /var/spool/virtual/passwd

#and the ls -l of /var/spool and /virtual:
drwxr-xr-x  23 root root  4096 Jan 31 17:26 var
drwxr-xr-x 16 root root   4096 Jan 31 18:56 spool
drwxrwxr-x 109 vmail  vmail  4096 Feb  1 00:33 virtual

the format of the file is similar to this:
fake at example.com:{PLAIN}pass
adam at example.com:{PLAIN}text


I tried searching first but couldn't find anything other than similar config
examples that seemed to confirm my config was setup right.  Any suggestions?

You really should go ahead and update to a release version... check the 
atrpm repository...

SELinux prevents accessing it.

Thanks Timo

For testing I tried:
#echo 0 >/selinux/enforce
and I got
Feb  2 05:00:31 ns2 dovecot: Dovecot v1.0.rc15 starting up
Feb  2 05:00:32 ns2 dovecot: auth(default): passwd-file
/var/spool/virtual/passwd: Read 971 users

so it worked.  The problem is identified but does anyone know how to permit
dovecot to work with selinux turned on?
