blocking junk mail

[Mark]

I am getting a bunch of emails with a blank in the name but when I go to
options I see the sender. Is it possible to block emails that come in with
a blank in the name are or can you block ".biz" from being received.

While I can't think os what may be causing your first problem, you can
address the second one with a rule that looks for ".biz" in the message
headers.
