Bonjour,
Très fréquemment, mes mails ne parviennent pas à leur destinataire si c'est une boite hotmail, avec le message:

This is the mail system at host mwinf4911.voila.fr.
I'm sorry to have to inform you that your message could not be delivered to one or more recipients. It's attached below.
For further assistance, please send mail to postmaster. If you do so, please include this problem report. You can delete your own text from the attached returned message.

Comme je n'envoie pas de spam, qu'a ma connaissance je n'ai pas de virus, que je n'ai aucun problème avec les autres boites que Hotmail, merci de m'indiquer la solution. rorosib66
