Missing add-on domain in email config

[Solokron]

I have a user that has an add-on domain that is not appearing in the drop down when he attempts to create a new email account.

Where is this list pulled from?

How can I resolve?

Thanks!

/etc/valiases ?

The domain is a whopping 30 characters before the TLD would this be a problem?

/var/cpanel/users
It is!

Solved.
