Hi All,
I have a Roundcube running in a DMZ (192.168.3.X/24)
This is a local mailserver which sends via an external MX (responsible for domain 'example.com')
The local domain is 'mail5.mytown.example.com' which is only a local domain
The internal network is (192.168.1.X/24) ('mytown.example.com')
All works fine sofar (sending and receiving mail)
But now I want to use logwatch together with nullmailer to send logs from the fileserver.
This causes an error in mail.log
NOQUEUE: reject: RCPT from unknown[fileserver's IP]: 450
I tried to add the internal network to the mynetworks in postfix's main.cf with no success
Any suggestions?
Marcovaldo
NOQUEUE: reject: RCPT from unknown[74.53.59.133]: 450
