Question

I am having problems with setting up a mail server on my droplet. here are my confusions

When adding an mx record, I am asked to add something like mail.sitename.com, my question is how do I setup this sub-domain or is it set setup automatically?
I have already installed postfix and dovecot but I cant receive any emails sent to the created address during configuration
How do i install roundcube to my droplet, I have seen varying tutorials on this and its getting confusing

I am running Ubuntu 14.04 on my digitalocean.

Thanks.

To create a record your MX record can refer to, you must create a A record.

You would go to the DNS panel, select the record type you want to add (A/AAAA/CNAME/etc.) and then add the correct IP/names.

DNS record:
host.name.here 14400 IN MX 0 name.here.

(including dot at the end)
14400 - TTL
0 - priority of the record, one can create multiple records
