In the sited example, yes, the PTR is set by the ISP and not delegated
to the spammer, but a pattern is a pattern and that's what we're here
for. Plus, for all we know, the ISP has a web interface for setting
PTR records rather than using delegation.

its not fqdn with just a dot, is your mta sendmail ?

Yes, but I like to test in SA and consult peers before putting a boolean axe in sendmail.

and my isp sets my ptr yes, but thay will have to make sure i did add it
as a a record first, the spammers isp above is clueless in that term

i think its the way it should be in a perfect world

Agreed, and that's how I run PTR records on my network. Plus, I cron checks that the PTR records continue to match over time.
