how to start postfix ?

strongzzj · 04-28-2005, 08:51 PM

I have killed the sendmail and started postfix,
but, I cann't telnet to 25 and 110.
Please help me,,,,thanks..

Obie · 04-28-2005, 10:04 PM

Did you check if you could telnet whilst running sendmail? How did you start Postfix? How do you know Postfix is running?

strongzzj · 04-28-2005, 10:41 PM

sendmail can't also.
use command start postfix: /etc/rc.d/init.d/postfix start
use command check if running:chkconfig --list|grep postfix.

Obie · 04-28-2005, 11:32 PM

Ok. Did you checked if telnet is blocked by your firewall? e.g. iptables --list

strongzzj · 04-28-2005, 11:49 PM

iptables was opened ,now is closed(service iptables stop),lokkit is closed also.but ,I can't telnet.

something useful:
The netstat command will show you which ports your computer is trying to listen on.

Code:

netstat -l -n

Then just look for :25 and :110

strongzzj · 04-29-2005, 01:51 AM

the port 25 is listening.
we must be telnet to 25 if everything was well.

Obie · 04-29-2005, 02:02 AM

can you telnet into your ISP's mail server?
Another thing are you trying to telnet to the same machine that runs Postfix?

strongzzj · 04-29-2005, 02:18 AM

I can telnet into others mailserver that runs MDaenon.
I only have one postfix server .

BinaryBob · 04-29-2005, 02:44 AM

Let's see the output of:

Code:

iptables --list -v

(Please look through it a bit first, it may contain data you consider sensative)

strongzzj · 04-29-2005, 02:56 AM

It is......

[root@mail ~]# iptables --list -v
Chain INPUT (policy ACCEPT 0 packets, 0 bytes)
pkts bytes target prot opt in out source destination

Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)
pkts bytes target prot opt in out source destination

Chain OUTPUT (policy ACCEPT 0 packets, 0 bytes)
pkts bytes target prot opt in out source destination
[root@mail ~]#

P.S: Iptables has been stopped.

BinaryBob · 04-29-2005, 03:15 AM

Ah, forogt that tid bit, ok not a firewall issue.

I haven't configured postfix before, but lets take a look at the config file maybe. There could be some things there.

I looked at: http://www.postfix.org/basic.html

and found this

Quote:

What clients to relay mail for
By default, Postfix will relay mail for clients in authorized networks.

Authorized client networks are defined by the mynetworks parameter. The default is to authorize all clients in the IP subnetworks that the local machine is attached to.

Are the machines you are telnetting from/to in the same subnet ?

*shrug* Longshot...

strongzzj · 04-29-2005, 03:37 AM

yes, in the same subnet.
oh ,what happen
