So weit ich weiß gibt es bei razor, bzw. bei der open source Alternative pyzor keine false positives. Es wird also keine richtige (nicht-Spam) Email als Spam erkannt. Bzw. die Wahrscheinlichkeit geht gegen Null.
Das kann ich bestätigen. Die Wirkung des Filters ist absolut überzeugend. Ich habe im letzten Monat ca. 10000 mails durch meine spamassassin laufen lassen, es ist definitiv keine Falschmeldung entstanden, einige, sehr wenige Spams sind unerkannt geblieben. Hier mal ein Bsp wie spamassassin eine mail markiert, am konkreten bsp einer gestern hier eingegangen spam-mail: source-code (ausschnitt) der mail:
