Problem with mail campaign planification

[Liior]

Hello, I'm on a SugarCRM 5.1

When I create a Campaign with the Wizard, I specify what mail I want to send, and what day and at what hour will the campaign begin.

But sugar does not send the mail.

Do you have an Idea ?

Thanks

Where could it come from ?

Did you add the cron.php file into your crontab ?
