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.
