Email Account Limit

[foodfor2]

Hi,
I can only create three email accounts through X10 for my domain name. When I try to make more it says "Warning: You are currently using the maximum number of Email Accounts. If you need more please contact your service provider." Who do I contact? My domain is through 1and1. I was able to create one email through them, but they want to charge for creating more. Is there a way to make more addresses through x10? Or another way for free?
Thanks!

Our current limits on free hosting for email accounts are set at 3; to change this you could sign up for Prime under the Upgrades option at the top of the page after signing in, this would double it to 6. You could also check into the Premium hosting service itself which I believe is unlimited in amount of emails allowed, although I'd recommend contacting premium staff first to confirm if this is accurate.

Ah, thanks.
Any other suggestions or workarounds?
