[Evolution] no passwort remembering while mail check

[Andreas Plank <andreas plank web de>]

Hello list,

I'm using ximian evolutoin 2.8. Every time evolution wants to check my
mail accounts (every 15 miniutes) I have to type in my passwords to get
connected to my mail servers. I've checked "remember this password" but
evolution won't remember next time. Is there any solution? 
Before the upgrade to evolution 2.8 this checking ("remember this
password") was working.

Any sugestions?
Thank you
Andreas

PS.: I searched also in this list, but the tips did not help.
