Getting error when trying to set default email for account using Cpanel

[wacnstac]

I'm getting the follow error when trying to set the default email for an account via cpanel.

All unrouted mail for ohiosportsman.com is now going to: webmaster@domainname.com
Fatal! Write Failure: /etc/valiases/domainname.com. Ignore any messages of success this can only result in failure!

What does this mean and how do I fix it?

It is there but weird thing is that it lists out as:

-rw -r--r-- 1msports msports date/time ohiosportsman.com

The weird thing about this listing is that this domain name should appear under the osports account. This is probably the root of the problem but I have no idea how to fix it.

How do you do that? Bear with me I'm a Unix and WHM newbie. My site had always been on a shared managed server before now.
