You can get the settings in XML format for all of your email accounts using RapiConfig on your computer. Setup your email accounts, then use RapiConfig to pull the info needed off of your device. You will have to change a couple things and add in your password info, but you should be able to setup any email account that way, even a Windows Live account.
See here for RapiConfig, and see the
thread at XDA for more info for setting up customization XML files.
