It's ridiculous to put in meaningless PTR records (the kind that just have an
IP
address embedded in them) just so that stupid filters that check for the
existence of PTR records will think they're valid. It just gives more
appearance of credibility to a check that never was meaningful in the first
place.
That's why most receivers put in logic to ensure the PTR was valid AND
meaningful long ago.
He got that resolved, but today, if you want to setup an MTA to send out
mail, you have no choice but to make sure the machine IP has an PTR record.
... and to kiss the assess of the RBL operators, and to pay tribute in any
number of other arbitrary ways to others who threaten to sabotage your
outgoing mail.
Seriously? You still view that DNSBL operators function in that fashion?
