We have just built a new Exim SMTP server, registered an mx record setup rDNS and a A record for our domain but certain mail servers are marking our messages as spam...
Cant see where we are going wrong.
(A) mail.citizen.net.au > 220.127.116.11
(MX) citizen.net.au > mail.citizen.net.au
(PTR) 18.104.22.168 > mail.citizen.net.au
Also im pretty sure our SMTP greetong is set to maxmailproxy.citizen.net.au - when i telnet to 25 internally i get what looks like the correct greetiog, but from external its just a bunch of ************** - which i think was done for security reasons??? does that matter?
what am i missing?
