I've been checking our newly configured DMARC status on the
(excellent) dmarcian.com site. We're being joe jobbed every 2 weeks so
I'm hoping DMARC severely cuts into that spammer's delivery success. I
still hate getting all the undeliverable bounce notices though.
In addition to what has been said, keeping "false bounces" at bay is
best done by implementing SRS/PRVS/BATV: it creates time-limited
"envelope from"-addresses and you can reject any null-sender message
directed at a non-{srs,prvs,batv}-addresses...
Which violates the RFCs, and causes all sorts of problems.
Null Sender addressed email != bounces
Null sender addressed email is any email that is automated where one
wishes to avoid mailing loops such as bounce messages and robot
generated messages... Or webform triggered registration email validation
emails where not an insignificant number are deliberately fake and/or
have typos... for example.
