Joe,

Nice, why bother advertising such a removal via email?

Because everyone is really meant to also own a Hotmail, AOL, Yahoo, gmail, or some such "reputable" email service that 
you use for instances like this.

OR... set your outbound SMTP server to your upstream's so that at least this message goes out correctly.  In your case 
(for 24.61.68.177) you would use Comcast's SMTP name, whatever that is.
