I am trying to set up CiviMail however I cannot seem to get my emails to go. They remain scheduled.However, when I execute them manually at administer->system settings-> scheduled jobs they go. When I click the edit button , no matter what selection I make on run frequency, that is hourly, daily or every time cron job is run, the emails are never sent.(Until I choose execute now option). I have tried reading on setting up a cron job and managing Scheduled Jobs but can not really understand. I am running CiviCRM 4.6.3 and Drupal 7. I have admin privileges and can access command line if need be.
I sounds like you either don't have a cron job configured to run the Scheduled Jobs at regular intervals, or you don't have it configured correctly.
What have you tried using as the cron command when you tried to set that up, and/or what errors does it give? (Edit your question above with further information)
