Email alias from 1 domain to another

OK, I like the idea of being able to setup alias, etc. The only problem that I have found is that I am unable to take one of my other domains and make aliases for them (or I haven’t been able to figure it out). What I’m ultimately looking for is to setup a couple of aliases from one domain that I added and have those addresses forward to my main Email account on my main domain.

Any help would be greatly appreciated. =O)

Nevermind, I figured it out. You have to select your domain under the Domains tab and then go to mail. Duh. What was I thinking? lol
