cron job is not working

Hello,

i have some troubles with the cron job.

i have done everything like recommended in documentation
Cron seems working both directly by url (Cronjob processed) or by cron (see log email below)

BUT the email are still pending in backend ! none sended !

Any idea ?
thanks in advance
Loïc
