 Posted: Fri Dec 05, 2014 10:33 am Post subject: [SOLVED] Postfix SMTP server unreachable outside of LAN |
 |
|
Hello,
I'm trying to setup postfix on my dedicated server, the daemon is running and working ( i can send mails from command line when i' ssh'd on the server ) but i from outside i can't see the open SMTP port.
postconf -n:
| Code: | command_directory = /usr/sbin
config_directory = /etc/postfix
daemon_directory = /usr/libexec/postfix
data_directory = /var/lib/postfix
debug_peer_level = 2
debugger_command = PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin ddd $daemon_directory/$process_name $process_id & sleep 5
home_mailbox = maildir/
html_directory = no
inet_interfaces = all
inet_protocols = ipv4
local_recipient_maps =
mail_owner = postfix
mailq_path = /usr/bin/mailq
manpage_directory = /usr/share/man
mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain
mydomain = my_url.com
myorigin = $mydomain
newaliases_path = /usr/bin/newaliases
queue_directory = /var/spool/postfix
readme_directory = no
relay_domains = $mydomain
sample_directory = /etc/postfix
sendmail_path = /usr/sbin/sendmail
setgid_group = postdrop
unknown_local_recipient_reject_code = 550 |
And the output of nmap:
From LAN:
| Code: | Host is up (0.0000090s latency).
Not shown: 992 closed ports
PORT STATE SERVICE
21/tcp open ftp
22/tcp open ssh
25/tcp open smtp
53/tcp open domain
80/tcp open http
443/tcp open https
3000/tcp open ppp |
From outside:
| Code: | Host is up (0.043s latency).
Not shown: 990 closed ports
PORT STATE SERVICE
21/tcp open ftp
22/tcp open ssh
53/tcp open domain
80/tcp open http
135/tcp filtered msrpc
139/tcp filtered netbios-ssn
443/tcp open https
445/tcp filtered microsoft-ds
3000/tcp open ppp |
Same for ping and telnet, i can reach my HTTP server but not the SMTP.
I can't paste postfix log ( dont really know why but they are not generated )
Can someone see why this is happening, and how to fix it ?
Thanks in advance.

| netstat shows an open smtp Port, so most probably you have some iptables rules in place. |

I have already looked at that, my iptables seems empty :/
iptables -L :
| Code: | Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination |
