Hello,

I'm actually trying to setup a mail relay with postfix 2.0.6, and I'm having few
questions. This relay will be put in DMZ, it has to accept external mails
(coming from internet) for recipients belonging to mydomain.org and
beta.mydomain.fr and redirecting it to a specific mailserver. It also has to
accept internal mails (coming from some servers of a specific network) to
external accounts (internet).

To do this I was thinking of setting in main.cf

mynetworks = "trusted networks"
relay_domain = mydomain.org,beta.mydomain.fr

and in transport :
myrelay smtp:[destination smtp server]

Is postfix making a reverse DNS verification on the helo client command, to be
sure that the client really belongs to the network it says it is belonging to ?

Thanx a lot in advance

Regards

Nicolas PEYRESAUBES
