SMPT-Mailtest works, but not from CiviMail

[Onsemeliot]

I'm experiencing a strange problem: If I send a test mail from the Outbound Email settings page: (site.com/drupal/civicrm/admin/setting/smtp) it arrives, but if I send a testmail from the last step of the massmailer (site.com/drupal/civicrm/mailing/send) it just doesn't arrive.

I would get it if no email could be sent at all. But I do not get why it works from one script, but not from an other one in CiviCRM.

Can anyone give me a hint what could cause such a problem?

The actual sending from Testmails or 'Mails from Search-Result' happens immediatelly. Those work without CRON-Job.

The actual sending of bulk-mailings (Mass-mails from CiviMail) happens by a CRON-JOB. See: 'Administration'->'...">'Scheduled Jobs'

There, you find the Job called 'Sending Bulk Emails' and you can execute this JOB directly there, so that the bulk-email-sending happens. (For many mails several Execute might be needed.).

Hope that helps!
