Set any of the following preferences:
Get indicates whether to get message
subjects only or entire messages.
Ask Every Time indicates whether you want
to see a dialog box for choosing subjects
only or entire messages each time you
retrieve email. If the box is unchecked,
messages are retrieved according to the
option you select in the Get pick list.
Unread messages downloads only unread mail to your device (IMAP
accounts only). If you don't choose this option and you select Get & Send,
all your messages on your provider's mail server are downloaded to your
Inbox, including messages you have already read.

To receive notifications of successful Auto Sync retrievals only, uncheck
the Alert me of failures box. Leave the box checked if you want to receive
notifications of both successful and failed Auto Sync retrievals.
The POP protocol does not support retrieval of unread mail only from
the server. If you have a POP email account, the Unread messages box
does not appear on the Incoming preferences screen, and VersaMail
downloads all messages regardless of whether you have read them.
