i havent tested thunderbird or eudora yet(will try them soon), but thanx to an advice from dexter, i tried ePrompter and man does it rock....supports pop3, yahoo, rediffmail, hotmail, lycos, etc...and u can add upto and send and recieve mail from 16 ids.
no eyecandy and u cant see the pix and flash on ur mail, but if u want a simple and efficient email client, ePrompter IS TH BEST.
