You are perfectly correct. Adding the entry to the MyAutoBL will not alter what SpamFilter does, so the emails will still be delivered to your Inbox.

The use of this extra table was added per user request, and as it does indeed help cleaning out the user's quarantine a bit, we liked the idea as well and implemented. It is was in no way meant as a means to actually block emails, since that was done already by the existing emails/domains blacklists. This MyAutoBL would however be more specific and could pinpoint blocking specific emails to specific users however... so we may have SpamFilter use it in the future as well to block incoming spam as you're hinting!

 

Roberto,

 

  We've been hinting this for years. Maybe we were hinting incorrectly

We're "trying" to release a new, long overdue, official build within the next couple of weeks. We've always postponed this as new features are continuously added, making it hard to have a "stable", proven build ready. If you can ping me back in 304 weeks, we'll see what can be done for this latter request.
