i got this message from everyone.net

Hello Hosting Company,

Please make the following change/addition to the DNS file:

colorsbox.com. IN MX 0 sitemail.everyone.net.

and i try to add mx record at raq's control panel but i confuse i must do Delivery Precedence to very high or very low or anything else

i hope someone can give me some answer for it

thanx u

I don't think you can set priority 0 from the control panel, best is "very high", which results in priority 20 (while very low is 50).

But if there aren't other MX settings with higher priority it should do the trick.
