Hello

I only want to inform you that the activation-email to register for this board was marked as Junk from my Thunderbird Email-Client. And I guess I manually only marked once an email as junk so my own filter rules can't be that huge ...

When you mark a message as junk in Thunderbird it doesn't so much create a hard "rule", it's more like training a monkey to recognize spam, just by telling it, this is spam, and this isn't (i.e. marking a particular message as spam doesn't mean it will only recognize that message as spam the next time; it will take all characteristics of the email into account and use it to check other messages as well).

I'm not sure how well trained the spam filter that comes with Thunderbird is by default nowadays, but when I personnally first started using it I had to correct it quite often.
