I've set up Postfix on a VPS running Centos 6, and I can access webmail using Squirrel Mail fine. But when I send or receive emails from my Gmail and other personal account I don't receive them on the VPS. I get no bounce back messages either.
What could be the cause?
I had an issue before with MX records and DNS, and these were resolved, hence why I didn't supply details of them.
Here are the records I have for my server:
NS ns1.6sync.net. NS ns2.6sync.net. NS ns3.6sync.net. ftp A 126.96.36.199 gravex.co.uk. A 188.8.131.52 gravex.co.uk. MX 10 mail.gravex.co.uk. mail A 184.108.40.206 setanta A 220.127.116.11 www A 18.104.22.168
I'm 99% sure these records are correct, as when I tried to send emails before I would get a DNS error bounce back. I don't get these any more.
