Actually you usually do. When anyone does a reverse lookup on your IP, it will
point at the ISP's DNS, not yours, so unless you have reverse delegation set up
on your ISP, creating your own PTR record is ineffective. To this end, most
hosting ISPs (certainly all of mine do) provide a facility to configure reverse
DNS entries in their name servers.
what you you smoked to only quote the part of a sentence which makes no
sense alone - I SAID "frankly SPF is no rocket science and you don't
need your ISP to configure that simple DNS record for your own domain"
so IF YOU DON'T be able to get your ISP change the PTR of your
mailserver to match your maildomain AND you areg ignorant in case of
make it do dnswl.org THEN setup SPF
if you don't bother about PTR, SPF AND DNSWL you don't care about your
outgoing mails - feel free to do so - but accept that other calling a
mailadmin not take care of that incompetent for good reasons and i don't
care how many and who agress in that point
