Postfix forward
 

I'm using postfix as a receiving mail server, i wanted to forward all incoming mail to an other host, what do i need to change for this.

The easy way to do this is to add the following to /etc/postfix/main.cf:

transport_maps = hash:/etc/postfix/transport

And then create the /etc/postfix/transport file with the following type of information:

server1.whatever local:
server2.whatever smtp:[111.222.333.444]
server3.whatever smtp:[server3.whatever]

OK, i have added the line in the main.cf and have created transport with the following lines

<localhost name> local:
<domain name> smtp:[192.168.0.80]

I wanted all mail received on the local host be forwarded to 192.168.0.80, will it work this way ?

put this in your main.cf:
Or even better, use postconf to alter the settings for you (-e for edit) - like this:
Then, to make them take effect do:
*If postfix is running:
or
*If postfix isn't running:
*Note: The reason I put in the 'mydestination' parameter is to show you that it shouldn't have $mydomain listed, since that's listed as 'relay_domains'.

With this script the messages are forwarded, but when someone outside tries to connect to send a message a relaying is denied message is served.

So only local generated messages are forwarded, when come from the internet they are denied.
