mailbox transfers, mx info

[Matt]

You need to tell the other host to make MX records like so:

yourdomain.com in MX mail.yourdomain.com
mail in A 111.111.111.111

Where 111.111.111.111 is your server at GlowHost's mail server IP.

Of course you'd need to setup a cpanel account for this domain and create the mail addresses, etc.
