postfix sending but not recieving

Hi all,

I'm having a issues with my new install of postfix. Its running on a Centos 5x server with webmin installed. I can email out of the server no problem but somehow can not receive email. I can telnet into port 110 fine but I cant telnet into the 25 port. The server is behind a router using NAT and I checked the routers firewall just to make sure its letting in port 25 traffic and it is. Could it be that my mx record is not right? When I do an mx records search I get no result but here is my mx record settings

mail.mydomain.net

MX

63.xxx.xxx.10

10

3600

Does that seem right? Would I have to make a CNAME as well for the mail.mydomain.com? Also is there another place I can check to see if port 25 is open on the server?

Thanks!

UPdate: I can telnet into port 25 on the box itself but not from the outside world.

sounds like 2 seperate issues. first port 25 isn't open to the machine. and then if your mx record isn't correct then others just won't be able to find you.

can you telnet to port 25 from any other machine on the same network?

No i cant I just tried it. just tells me the connection failed.
Could it be an iptables issue?

thanks

I am able to ssh to that server from another box on the network.
but i cant ssh outside the network..

well I wouldn't say open ssh to the outside, that won't help this situation.
open /etc/postfix/main.cf
and tell me what the line

Code:

inet_interfaces =

naa

I was going to suggest that...

inet_interfaces = all (try that for testing)

then do a postfix reload

I'll just post the whole cf file

My bad I misread

Code:

#inet_interfaces = all #inet_interfaces = $myhostname #inet_interfaces = $myhostname, localhost inet_interfaces = localhost

so just edit this line for =all?

inet_interfaces = localhost

or just uncomment this line

#inet_interfaces = all

?
