postfix question

hi,

sorry for my bad english but I try to explain my problem

so I have a server foo.com link to external on eth1 with a ip
on the second network card eth2 I have a static ip 192.168.1.205

with ip_forwarding enabled

the eth2 go ton a switch

and a second server bar.local is connected to the switch with a static ip too 192.168.1.20

on the bar.local server I can ping google

my question is can I install a postfix server on bar.local server for send outgoing and receive incoming mail from public network?

if yes how can I make that?

 

You'd have to configure foo.com to forward port 25 to bar.local. You can do this with iptables, e.g. like this:

Code:

iptables -A PREROUTING -t nat -p tcp -i eth1 --dport 25 -j DNAT --to 192.168.1.20:25

 

thank you very much for your help and your tips.

 

so I have an error when I try to receive a mail from network

I can't send a mail from network to my server

so when I send a mail from gmail to my postfix server with this [email protected] I didn't receive the mail?

any idea?

 

Any errors in the mail log?
