Hallo zusammen,
wir erhalten seit einigen Tagen Dropbox Spam, der leider nicht als solcher erkannt wird:

Code:

Code:

* Häufig wird Spam, der mit bloßem Auge erkennbar ist, nicht aussortiert. Beispiel von oben:
1710257993665.png
* Um unsere User weiter schützen zu können, suchen wir nach einer Möglichkeit, Links in Emails, die von Extern kommen, nicht mehr klickbar zu machen.

Habt ihr spontan irgendwelche Ideen?

Ich würde empfehlen Bayes zu deaktivieren (ist seit 8.0 auch der default-wert) - bei dieser mail wurden 5 punkte abgezogen wegen dem (nicht trainierten Bayes filter) - dann sollten die mails auch als spam erkannt werden.

Ich hoffe das hilft!
