Well I already filter by putting it in a different folder. But I want to perminently stop certain email addresses from coming in at all. So is it best to do this at the maildrop level or does qmail have something built in that better "blocks" certain email address?
Yes, it's best to do it at the maildrop level.
BTW: Please check the time on your computer.. It's set in the future. :)
