Hi Team,
Moved from cPanel to CWP recently. Setup CWP on Linode.
PHP emails are working and in the queue, but I am getting timeout errors.
For example, timeout errors on Google lookup:
===================================================
connect to alt2.aspmx.l.google.com[2607:f8b0:4023:c0b::1a]:25: Connection timed out
===================================================
More logs:
===================================================
Jun 24 06:01:41 dev postfix/smtp[4120]: connect to aspmx.l.google.com[2404:6800:4003:c02::1a]:25: Connection timed out
Jun 24 06:01:41 dev postfix/smtp[4142]: connect to aspmx.l.google.com[2404:6800:4003:c02::1a]:25: Connection timed out

Jun 24 06:02:14 dev postfix/smtp[3885]: connect to alt2.aspmx.l.google.com[2607:f8b0:4023:c0b::1a]:25: Connection timed out
===================================================
I've updated the DNS to be CloudFlare followed by Google with no luck.
Not sure if it is possible a firewall issue? Seems like Port 25 is being blocked and timing out? I don't have any restrictions on Port 25 at this stage.......
Any tips would be great or if you need any other logs.
Thanks.

http://forum.centos-webpanel.com/index.php?topic=10765.msg37109#msg37109 - This could be the issue since moving Linode.
I have submitted a ticket with them.

Got Linode to unblock the ports and good to go!
