I am using Amazon Route 53 and have a correctly functioning A
record pointing to an EC2 instance at mydomain.com.au
with a Django stack running.
My problem is, I tried to setup a Postfix mailserver but I could not receive mail, so I figured my problem is with the MX
record (since local mail worked).
This is what I have got for my MX
record and just wanted to confirm if it is correct, or if it's nonsense:
(Settings as per AWS interface)
Name: left it blank (mydomain.com.au)
Value: 10 titan.mydomain.com.au
I have used "titan" because it's the hostname of my server - should I use "mail" instead? I keep seeing this on the web but can't find an explanation of if it's arbitrary.
I want the e-mails to work such that user@mydomain.com.au
gets delivered to the server.
I have looked at this question and this one too, but didn't find an answer in them.
