I've been trying to send mail to my new postfix configuration from my yahoo and gmail accounts and so far it has been nothing doing. On my Amazon Route 53 I have my mx record listed as:
however, when I try to netcat:
nc mail.example.com 25
getaddrinfo: Name or Service not known
My domain was bought from NameCheap. Is there anything I have to do on that side? My website works flawlessly on Apache, but I don't even get errors in my mail log when sending with gmail and yahoo. I have ports
465 open on my EC2 server, but I do not have SSL or any kind of encryption scheme on my server.
