Spam and Blind Carbon Copy Bcc:

Question

Apparently one of the ways spam is sent and bypasses filter rules is to put fake email addresses in the Cc: header and your real email address in the Bcc: header. I set the rules filter to only accept an email when the To: header or Cc: header has my real email address listed. Apparently, the Mail filter actually reads the Bcc: header as if it is the Cc: header since spam emails addressed to nonsense addresses keep getting through.
Is there a way around this problem. Can apple adjust the Mail filtering system, or do I have to block the Cc: header as well to actually prevent Bcc: addresses from being delivered to me?

Answer 1

I may have a much simpler rule to deal with Spam and Junk mail that you want to try:
If (any) Sender is not in my address book
Move Message to Junk Mail (a folder created on my Mac)
Stop evaluating rules.
Since these mailers are certainly not in your address book, you only have to give it a quick glance to see if any of these messages could be from somebody you know, and not yet in your address book. Then I delete them all, without looking at them.
Of course this requires you to keep all your known contacts in the address book. It works great for me, just wanted to share this with you.
