JMail - Envoi de mails avec pièce jointe

Présentation

Ce script est l'équivalent de la commande mailx, mais ajoute la possibilité d'envoyer des fichiers en pièce jointe au message.
 
La syntaxe est la suivante:
jmail -s "Sujet du mail" [-sender adresse_mail_emetteur] [-html] [-cc adresse_mail_en_copie] [-j fichier_a_attacher] adresse_mail_destinataire
L'option -html permet d'envoyer un mail au format html
L'option -cc permet d'ajouter des personnes en copie du message
