* If you are searching for messages anywhere on the system, whether they
are in your mailbox or not, then a date range is mandatory, and defaults
to the last 30 days, which you are free to change. (If you are only
searching your mailbox, then these are optional.)
You may specify approximately when the message was sent.
- Enter the 'DA' ('Message sent on or after') search action code
to enter the lower end of the date range.
- Enter the 'DB' ('Message sent on or before') search action code
to enter to upper end of the date range.
