Would you care to expand on why you think sender callback  
verification is apparently abusive and supports spam?

I sure don't mind my MXers being probed if it stops somebody forging  
mail from my domains.

What next, will forward lookups of rDNS to verify that they're not  
forged also be considered abusive because the forged third-party's  
servers get consulted out of paranoia?
