I have Postfix on an Ubuntu server.
postconf mail_version
mail_version = 3.6.4
Every email i send to any recipient ( tried gmail , hotmail and yahoo ) , is stuck in the queue
(connect to alt2.aspmx.l.google.com[2404:6800:4003:c00::1a]:25: Connection timed out)
Is it a conf issue?
My conf:
postconf -n

Also i have tried this and it seems to be stuck , no answer , and i have to CTRL+C
openssl s_client -connect alt2.aspmx.l.google.com:25 -starttls smtp -crlf
If i do the command above from my local computer , it works.
This is what i get with traceroute from server
traceroute -p 25 alt2.aspmx.l.google.com
traceroute to alt2.aspmx.l.google.com (74.125.200.26), 64 hops max

I still have not configured a PTR record , but i think if that was the problem , i should get a different error , right?
