Mail can't receive.

Hi,

Regarding the port 25 issue , I've updated the details.,

[root@server ~]# iptables -L -n
Chain INPUT (policy ACCEPT)
target     prot opt source               destination
ACCEPT     tcp  --  0.0.0.0/0            0.0.0.0/0           tcp dpt:587
ACCEPT     tcp  --  0.0.0.0/0            0.0.0.0/0           tcp dpt:587

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination


[root@server ~]# netstat -an | grep :25
tcp        0      0 127.0.0.1:25                0.0.0.0:*                   LISTEN

Howdy,

It appears that Postfix may only be listening on localhost, and not on your public IP address.

What does this command output:

grep inet_interfaces /etc/postfix/main.cf

You would normally want that set to listen on all interfaces.

Eric,

Thanks for the reply. Can please check the below snippet from our server.

[root@server ~]# grep inet_interfaces /etc/postfix/main.cf
# The inet_interfaces parameter specifies the network interface
inet_interfaces = all
#inet_interfaces = $myhostname
#inet_interfaces = $myhostname, localhost
inet_interfaces = localhost
# the address list specified with the inet_interfaces parameter.
# receives mail on (see the inet_interfaces parameter).
# to $mydestination, $inet_interfaces or $proxy_interfaces.
# - destinations that match $inet_interfaces or $proxy_interfaces,
# unknown@[$inet_interfaces] or unknown@[$proxy_interfaces] is returned

Ah, it looks like there are two "inet_interfaces" lines, there should only be one.

I would recommend commenting out this line:

inet_interfaces = localhost

And then restart Postfix:

/etc/init.d/postfix restart

After that, does your email work properly?
