Evolution no password prompt

I set up my account in evolution, i checked ‘remember password’ for both incoming(pop) and outgoing(smtp) mail. when i tried to send a mail i was prompted for my smtp password. i chose unsafe storage. but it never asked me for my pop password because of which i cannot access incoming mails. i used File->forget passwords and it didn’t prompt me again for my smtp password either. please help me out
i’m using opensuse 11.4,gnome,evolution 2.32.1
