postfix cannot send email
- by AKLP
I'd like to mention that im really new to this so please bear with me. I'm trying to setup a forum software to send emails via postfix but I think my server has the port 25 blocked. I tried running these:
works:
ping alt2.gmail-smtp-in.l.google.com
don't work:
telnet alt2.gmail-smtp-in.l.google.com 25
telnet 66.249.93.114 25
tried flushing iptables and then using these rules but didn't work either:
sudo iptables --flush
sudo iptables -P INPUT ACCEPT
sudo iptables -P OUTPUT ACCEPT
sudo iptables -P FORWARD ACCEPT
sudo iptables -F
sudo iptables -X
doing a telnet on 25 port to localhost url works but nothing when telnet'ing in none local urls.
