Unabler to send messages via Postfix
I’m trying to configure a postfix instance for a Discourse install. Everytime I try to send an email I get this error:
Aug 11 10:29:06 basquewaves postfix/smtp: connect to ASPMX.L.GOOGLE.COM[126.96.36.199]:25: Connection timed out Aug 11 10:29:06 basquewaves postfix/smtp: connect to ASPMX.L.GOOGLE.COM[2a00:1450:400c:c03::1a]:25: Network is unreachable
I tried the connection using telnet, and didn’t work neither. Is it possible that the port is closed ?
root@basquewaves:~# telnet aspmx.l.google.com 25 Trying 188.8.131.52... Trying 2a00:1450:400c:c05::1a... telnet: Unable to connect to remote host: Network is unreachable
Thanks in advance
