BATV stands for Bounce Address Tag Validation and VERP stands for Variable Envelope Return Path. The principle behind these two concepts is to validate the bounces you receive. Every time you send an email, you set the envelope sender address to a one-time address only valid for this message. If the message bounces to this one-time address, then you know for sure what message bounced. If a forged message bounce, then you know for sure that you never sent this message and you can bounce the bounce. It's like SPF classic but 200 lbs lighter. Of course, this implies that all of your outgoing email came from authorized servers (who had the BATV/VERP key).
