Nope, not yet.
I created a user called "spam" on my Freesco
and added a "redirect" in the aliasses file so the "spammed accounts" will be directed to the "spam" user.
Then in cron, I added a job to clear the "spam" users e-mail every week.
But for some reason, the messages still end up in my general mail box.
This could be because I have also added the "redirect all" to my main account.
But this line is last in the alliasses file, so I don't get it why it still redirects the spam mail to my general account and not to the "spam" account.
Unfortunately, I didn't have the time to dive further into this because of lack of time...
But I'll keep you posted.
