The language filter lets you automatically define email in specific languages as spam. For example, if in general you do not have email contact with a German-speaking person, then you can set German as a spam language which should be filtered out. Simply select the languages in which you do not receive regular email contact and the G DATA software will raise the spam probability for such emails.
Under Reaction you can determine what is to be done with emails identified as spam by the G DATA software.
Using Reject mail means the email in question will not even be accepted by your email program.
If you check the box for Insert warning in mail subject and text you can prefix the actual text in the subject line with a warning (prefix in subject line), e.g. Spam or Warning. You can also enter text to be placed above the actual email text in the event of suspected spam (Message in text).
If you use Microsoft Outlook (caution: not to be confused with Outlook Express or Windows Mail), you also have the option of moving emails containing suspected spam to a fully customizable folder in your mailbox (Move mail to folder). You can create this folder directly via the G DATA software by defining the corresponding folder under Folder name.
