I think we worked out that, in common with the hosting I use, your GoDaddy one uses CPanel, Joe. You would probably find a selection of email tools there.

You may also find that the chosen package does place some restrictions. With my hosting for example, I appear to be unlimited on the number of email accounts I can have for one domain so I could go ahead and add say jon@, joe@, dave@ chosendomain at will. I am limited to five (one main and four addon) domain names though and email usage counts towards my total disk usage.
