Endlich spamfrei leben. Das geht im Grunde nur mit einem professionellen Schutzsystem, welches die Mails analysiert und alle zur Verf\u00fcgung stehenden M\u00f6glichkeiten verwendet, um den Missbrauch der eigenen Domain zum Spamversand zu verhindern.

In der Regel wird lediglich der MX Record einer Domain auf den Server gesetzt, damit der Kunde \u00fcber die Domain auch eMails empfangen kann. Das bringt einiges an Gefahren mit sich. Denn das eMialsystem l\u00e4sst sich sehr leicht manipulieren. Es ist m\u00f6glich den Absendernamen einfach zu f\u00e4lschen. Man kann eine eMail abschicken unter einem beliebigen Domainnamen.
