So would a solution to the problem to make my RDNS say
mail.efastfunding.com(66.226.235.118
) instead of efastfunding.com(66.226.235.118)
In my case the only other thing I can do it put my mail server outside my
firewwall or to install a new firewall just for the mail server which is
kinda costly. If I must have DNS/RDNS both be the exact ip of the mail
server then how the hell to you this if you have dozens of mail server in a
company (ie hp.com,hotmail,yahoo,msn). I mean yes I exact a log error a
sstated in the RFC but does it not say you can't deny and yes my helo should
be stating mail.efastfundig.com which does resolve to 66.226.235.114 port 25
only.
I guess Tuesday I am going to change RDNS records and see what happens if
that doesn't work then it's breakout the OB box and build a firewall just
for my mail server so I can answer Greg's email.
Currently Comcast support has called me and is looking into why there mail
server are giving this error message since they could not find a reasaon why
before the holidays.
