2 things before I wash my hands of this.

1. You don't understand as much of SPF as you think you do.  A sender
need only insert an appropriate Return-Path: header, and they can send
messages as From: you without triggering SPF blocking at all.  SPF is
only useful to prevent backscatter.  (That is, a mail server that honors
 SPF will not send bounce messages to a forged From: address.)

2.  You lie with dogs, you get fleas.  I understand you had no malicious
intent sending your contact list to spammer scum like Linked-In, but if
you can't acknowledge the basic err in netiquette of sending off other
people's contact info like that, you fail.
