Hi,

I installed the EnGarde Secure Linux server.
and configure the postfix to send email.

i can send the emails on lan but
unable to send and recieve the email to/from internet domain.

anybody me to setup the postfix???

or send the main.cf file.

please email to shoaibm1@gmail.com

thanks in advance.

Run the command "postconf inet_interfaces" and make sure it is set to: all

Run the command "netstat -an" and make sure it shows it's listening on SMTP
port 25 on all interfaces (0.0.0.0) which should look something like this:

tcp 0 0 0.0.0.0:25 0.0.0.0:* LISTEN

See if your Postfix box can telnet to it's own SMTP port 25 on it's own
network IP address, and verify that it produces a Postfix welcome banner.

telnet xxx.xxx.xxx.xxx 25

Take a look at the syslog output for errors, usually in /var/log/maillog or /var/log/messages.


If everything worked okay up to this point, then try the telnet test from other machines
on your local LAN, and then from the outside internet.

At this point, it's probably a firewall/security config issue on your local (secure linux) machine
or external firewall, and not a Postfix configuration issue. I'm not familiar with EnGarde Secure Linux,
but to me, the name of it implies that it probably blocks all TCP/IP ports by default.
