How to enable multiple email domains under one login?

[cube]

I'm trying to figure out how to mod Rcube to send/receive multiple email accounts, from different/multiple domains. Anyone know if there's a way to do this? My goal is to be able to add multiple email addresses from multiple domains and have messages appear in one email inbox (and then messages can then be moved into my custom folders such as attic, etc.) I'm using Hostgator, who offers a default version of Rcube, but I can always install Rcube in a separate /dir on my hosted domain server. Thanks in advance for your help...
