Full-text searching

Users can now perform full-text searches on messages in their mailboxes.

Unlike the Find function, which only looks at some of the headers, the Search inspects the entire message body too. Searches can be run on a single folder, or on an entire mailbox.

Naturally this can be a CPU-intensive function, so this is disabled by default. Administrators can also set a millisecond timeout to prevent server overload, and may want to consider using a multiple-CPU server if this feature is expected to be used significantly.
