When I try to telnet to port 25 using this command:
telnet aspmx.l.google.com 25
I get this message
And nothing more happens. I disabled csf but the problem still exsists. I also asked my VPS co. whether they have blocked port 25 and they said they have not blocked any port.
In postfix logs:
server2 postfix/smtp: connect to alt2.gmail-smtp-in.l.google.com[18.104.22.168]:25: Connection timed out
Is it possible that google has blocked my server ip address?
Tried yahoo (
telnet smtp.mail.yahoo.com 25) and it has the same result. I also disabled iptables(
service iptables stop) but problem still exists.
