UPGRADING TO LOTUS NOTES 6 AND LOTUS DOMINO 6

Internet mail storage format in Lotus Domino 6
You do not need to change how users' Internet messages are stored when upgrading to Lotus Domino 6. If you have users who only access mail with a POP3 or IMAP client and whose Person documents set their Internet message storage to both Notes and Internet in Lotus Domino 4.6, changing the field "Format preference for incoming mail" on the Mail tab to "Prefers MIME" will improve performance, but increases bandwidth use and storage space.

In a mixed Domino 4.6/Domino 6 environment where some clients use native MIME messages on Domino 6 servers, Domino cannot deliver a native MIME message to a Notes 4.6 client, mail file, or server, because native MIME is unreadable in Lotus Notes/Domino 4.6.
