I'd definitely suggest checking with your ISP first. Unfortunately, someone (or many someones) are using spoofed wrox.com email addresses in a lot of spam. It might be possible that your ISP, or even an upstream ISP, is blocking some/all email appearing to originate from wrox.com including P2P email because of this.

If the ISP can't help and you still aren't getting the mail, let us know.
