Chap, this is so spammy - what dya need? Someone to punch you in the face? "Hello? I am SpamSpamSpam!"
I would never had opened that "nospam@blahblah"-email, never ever.
Try this:
Accept only emails from people you know/ emails you personally requested. Everything else is junk. (depends on your workplace[H]).
Also, emails without Verification/Authentification (PublicKey) is not trustworthy.
