Ο mail server μου έλαβε το μήνυμα για το χρήστη vicky, ο οποίος δεν
υπάρχει.  Αντί να επιστρέψει μήνυμα στον αποστολέα, έχει παγώσει το
μήνυμα και δεν το ξεπαγώνει.  Αν καταλαβαίνω καλά, αυτό οφείλεται στη
γραμμή 3 του επισυναπτόμενου αρχείου, που είναι ο "Sender", που έχει
την τιμή "<>".  Τι είναι ο sender; Είναι το περιεχόμενο του MAIL FROM
του smtp; Επιτρέπεται να είναι κενό;
