Email Auto Forward

I have signed up for hostgators webhosting.

Upon setting up, I found out that outgoing mails from any email addresses from my domain name cannot be copied to another email account. I've tried scripting on the client software (e.g)outlook. it works. but then again, it only applies on the client side if the scripted client is present. this would not work if the email is sent from the web based login.

is there a work around for it?

If there isn't, does any one know of any webhosting co. that allows that?

Situation is, my current host does allow it. Due to small amount of disk space allocated, reliability of the service, technical support and cost, we therefore have decided to switch to another host.
