MX Plan - Envoi en spam

Bonjour la communauté,

Je rencontre des difficultés pour l'envoi de mails automatique (confirmation compte, etc). Je bénéficie de l'offre Web hosting Perfx1 2014 (hébergement web sur cluster) ainsi qu'un MX Plan associé. Je souhaite envoyer mes message depuis SwiftMailer (projet Symfony).

Le problème semble provenir d'une mauvaise configuration du champ MX. En effet, lors de la réception des mails apparaît
`ne-pas-repondre@votremenuenligne.fr via mail-out.cluster028.hosting.ovh.net `

L'application test mailer confirme cet avis : rapport test mailer.

Au niveau du domaine, je dispose de l'entrée `TXT : "v=spf1 include:mx.ovh.com ~all"` (j'ai essayé de même sous format SPF sans amélioration).

J'ai contacté le support qui me laisse sans réponse. J'ai lu de nombreux sujets similaires sans trouver de réponses concluantes. La qualité de l'offre OVH est-elle en jeu ?

Merci de votre aide,
Alex
