The answer is no or at least not that I am aware of.
rDNS has to be setup. My e-mail server is rejecting any incoming e-mail
if the e-mail server does not have rDNS as in 99% cases this is spam.

I have a problem with email being rejected from one of our customers.
They do not have reverse DNS setup for their mail server. I have
explained to them why they need that and they are looking into getting
it fixed. Until then, is there a way to whitelist mail coming form
them so it passes through the rDNS check?
