The spam filters have generally worked reasonably well however the last few weeks weeks there have been specific pieces of spam that always made it through. Black listing the email address is pointless since the email address is never the same and domain blacklisting doesn't seem to allow me to block using TLDs. The email black list grows since I flag them all as spam but what's odd is the mail often times gets moved back to the inbox either immediately or hours later.
It would be nice to be able to blacklist IP ranges or even TLD's unless there is a way and I just don't see it but the same few pieces of spam always make it through the filters and it's just annoying now.
