Emails non désirés envoyés à mes contacts

Bonjour,


J'ai reçu des failure notices de mailer_ daemon@yahoo m'informant que des messages envoyés à un groupe de mes contacts n'ont pas été envoyé à x ou y. Le problème c'est le contenu (sites publicitaires pour viagra ou sites coquin) qui sont envoyés à l'ensemble de mes contacts. Cela fait 2 jours que ça se reproduit.
ci-dessous un exemple
Sorry, we were unable to deliver your message to the following address.
