It sounds like Cyrus is not running.  Hence the lack of logs.  Check
'/var/log/messages' for errors.

Since you are using Postfix make sure that you don't put cyrus in the mail
group. If you do you'll get an error:

  ...postfix/pipe[28807]: fatal: request to use mail system owner group id 12

What you need to do is create a cyrus group and add cyrus to it. You can
do this by adding --with-cyrus-group=cyrus option to the ./configure.
