Hi list,
I can't setup a ptr RR for my mailserver's IP.
Here the main ISPs who are owned by this garbage state take expensive price
for setup a reverse record for a public IP. It's about 30 USD each month
for each IP.
But some MTAs does require the peer deliveragent has a PTR RR,like AOL's
email systems.
Is there a special RFC for this requirement?
Regards.
