SpamAssassin Funktionality

Question / Problem

Why do I still receive spam mails when SpamAssassin in a Box was just installed?

Answer / Solution

SpamAssassin in a Box is not a mail router. This means, the included spam filter just scores mails that have been passed to it and reports the result back to the invoker. Therefore the mail server you are using has to support an interface to SpamAssassin in order to make use of it's spam filter functionality. If you use Microsoft Exchange Server, you should have a look at the Exchange Server Toolbox which is a completely pre-configured server add-on for Microsoft Exchange that already contains SpamAssassin, besides several other powerful features.
