/*
Diese Klasse liefert alle Methoden, um für mein Mailprojekt die nötigen Operationen bereitszustellen. Da ich unter großem Zeitdruck stehe,
verzichte ich auf Ballast wie Properties(getter und setter),Try/catch und Destruktoren, die hier durchaus Sinn machen würden! Außerdem implementiere ich
alle Methoden so, wie ich sie benötige. Ich berücksichtige beispielsweise nicht ,dass eine Verbindung auch ohne SSL-Zertifizierung möglich
wäre...Mein Nachfolger kann diese Features gerne einbauen!
Feedback oder Rückfragen bitte an:tklustig.thomas@gmail.com
