RC6 courier to dovecot

[1stknight]

Hi guys,

I am a newbie to ispcp... and i had rc6 installed.. and given that a lot is suggesting to move over to dovecot, i had dovecot installed....

i got two problems...
1.) mails don't get delivered
it gives out this kind of error
postfix/pipe[16591]: 50834B7C3F: to=<user@mydomain.com.ph>, relay=dovecot, delay=21, delays=21/0.02/0/0.03, dsn=5.3.0, status=bounced (Command died with status 89: "/usr/lib/dovecot/deliver"
2.) i cannot authenticate...
i kinda noticed in the suggested config the entry for password_query with
a mysql statement md5(mail_pass), but when i check on the mail_pass field
in the database it does not contain a plaintext file..
could this be the problem?
