so if i am not mistaken, when i enable my yahoo account using zimbra desktop, some data (email) is downloaded locally so that i can work on it while disconnected from the internets. that's very nice. my question is, is this data encrypted so that if i lose my laptop someone can't simply open the files and read let's say email addresses? my personal email has a lot of messages from my banks etc etc and if these emails are to be stored locally i want to know they are safe.

thank you very much!! zimbra has made me fall in love with email once again!!
