This post is similar to one of some days ago.
I want to add some important details.
This is my production configuration:
ISP (DNS manteiner) -> Firewall (public IP) -> Qmailtoaster server
(iptables natted private ip)
qmailtoaster is based on centos5 x86_64
I obtain this error with some destination domains.
<[EMAIL PROTECTED]>:
User and password not set, continuing without authentication.
200.44.aa.bb does not like recipient.
Remote host said: 550 5.7.1 <[EMAIL PROTECTED]>... 159.213.xx.yy does not have a
matching IN PTR Resource Record - Giving up on 200.44.aa.bb
The result of
"dig PTR mail.comune.follonica.gr.it"
is correct.
In my opinion the problem is in "Received" header line.
Below there is part of the reply message (the original mail was sent using
squirrelmail)

192.168.0.1 is the IP address of firewall (DMZ side)
Is there a method to force Received line to 159.213.xx.yy?
What's wrong?
Thanks.
