Bonsoir !

Je gere une boite à lettres Email de notre association des anciens eleves via WebMail d'Yahoo
J'envoie donc des prospectus à 300 membres ( en fait repartis en 5 groupes à cause de la contrainte imposée par le WebMail d'Yahoo )
Parmi ces 300 membres : il y a 15 membres qui ont une adresse @free.fr qui m'ont été retournés avec comme message
