Using GroupWise as a generic mail client

Tired of Thunderbird's quirks? Want something else but don't like either Evolution or Outlook? You have another option.

GroupWise@Home!

As near as I can figure, this is a GroupWise client tweaked for use without a GroupWise server. This'll allow you to do IMAP/POP email and have all those other nifty GroupWise features like richly featured rules. I haven't tried it myself, but I am sorely tempted.
