There are several ways you can do this.
My first attempt was to add the Mac account to my personal account. Gmail can support up to 5 e-mail addresses. If you have 5 e-mail account, you can pool it all into one.
After playing with the POP settings and checked with UTS, they did not offer the functionality at the time. However, I revisited this problem and looks like they have resolved the issue.
Try adding your account via personal Gmail and follow these instructions. It sure beats e-mail forwarding from your Mac Gmail.
