title: Review request and expiry notification emails for scheduled publishing pages
body: <p>I'm currently running a publishing portal in a small server farm environment. Using the page settings and schedule form for publishing pages we have configured our content to 'send a content review request mail to the page contact'. We've tried a number of different configurations for the frequency of the emails but no matter what we select, no emails ever get sent. The same thing appears to be happening to the expiry notifications.</p>
  
  <p>We've checked the email settings for the farm and they appear to be correct. Alerts and welcome emails are all functioning correctly. Does anyone know how to get these working?</p>
