Hi,

claws-mail is super nicelly written and has served my needs a couple of years at least.

If you'd like to help bringing a new facelift you can contact the developers at:
http://www.claws-mail.org/

A couple of them have been quite active here in the past.

IRC, lma has recompiled the app for maemo 5 but he was not planning to work more on it. If you search for thread title "claws" you find many discussions and the reasons the developers have decided to stop further development for maemo.

HIH
