FYI - Unless a newer version of Snapper has SSL, you will not be able to check gmail because it requires SSL on both incoming and outgoing. Versamail however DOES have the capability and I just tested it, works great.

Note: You must first enable the pop forwarding in your gmail settings.

Also, a nice little thing here. Any account you set up in Snapper passes most of your account settings to Versamail.
