I can't seem to figure out how to enable port 25 on Ubuntu. I tried to add it to IP tables like below:
root@plato:~# iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
ACCEPT tcp – anywhere anywhere tcp dpt:smtp
ACCEPT udp -- anywhere anywhere udp dpt:25
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
however to no avail. I have also tried to add the port to 58 in master.cf in the postfix config like below:
smtp inet n - - - - smtpd
58 inet n - - - - smtpd
But I still can't connect via telnet through either 25 nor 58. I can however connect through port 995 - is it possible to use this port instead?:
wire$ telnet mail.koop.hk 25
Trying 66.228.32.238…
telnet: connect to address 66.228.32.238: Connection refused
telnet: Unable to connect to remote host
wire$ telnet mail.koop.hk 58

inet_interfaces = 127.0.0.0/8
to
inet_interfaces = all
then restart postfix
service postfix restart
Actually the inet_interfaces was set to loopback-only - I changed it to all and than it worked.
Cheers!
