Configure reverse DNS on shared ip ?

[dahu]

Hi

a dummy question :

Is it a way to configure reverse DNS for shared ip ?

The problem (and i think im not alone)
- 50 account
-- 20 with unique ip
-- 30 on the shared ip (because ip block are not free and wasn't usefull for some website)

-the problem : Mail are now massively refused without a correct rDNS

Otherwise : a solution to use php mail() or smtp class to fix this ?

best regards

PS: i saw the RDNS tutorial post

Email always goes from the server main IP no matter the site is on shared ip or on unique IP and if you haven't made any custom settings in Exim.conf.So you only need the Reverse DNS for the server's main IP.
