Yes, there are a couple of ways, one using the DM backup/restore feature Advanced option. Setting the Clear Address Book option (I think that's how it's worded). The other is to highlight the first email in the message list you want to delete, then press and hold the ALT key while rolling the track wheel down to the last. The select delete messages from the menu.
Hope this helps.
BTW, I hope you feel suitably honored. You are the recipient of my one thousandth post on BBF.
