in reply to How I usually read my mail:

Just as a warning to anyone who was considering using Outlook Express - DONT! Yes, everything will work fine ... most of the time, but sooner or later you will realize that you want to get away from OE ... and you won't be able to because that mailbox format is proprietary (like everything else in MS) and its export tools are pretty poor. And God forbit you try to import that data into a non-MS mail client ... you're in for a surprise :-)
