I had a user that used to get Joe Jobbed constantly, mainly because he has a catchall (I know). I configured BATV for him and he stopped getting the bounces. Then I told him to configure SPF on his domains and after a month or two the Joe Jobbers stopped using his domains altogether. I could probably turn off BATV for him now because of that, but it's doing no harm. On my own email, I use BATV, SPF and DKIM and I don't use the testing modes. I don't get Joe Jobbed.
