Jetpack CRM et Gmail

Bonjour,
Pourriez-vous m’aider car je souhaite programmer l’envoi de mes mails à l’aide d’une adresse email Gmail et j’obtiens ce debug :

Jetpack CRM has tested your settings, and also tried probing your mail server, but unfortunately it was not possible to confirm a test email was sent. Please go back and check your settings, and if this persists please contact support, optionally sending us the debug output (click to view).GMail sometimes requires further steps to complete. Read the Gmail Setup guide.

Que puis-je faire?
Est-ce le fait d’être en local qui provoque ce problème ou non?
Merci pour votre aide.
