recover user mail

[Dave]

We recently had a user that lost all their mail. I have incoming
Mailscanner archives for 30 days. Has anyone seen or written a script
that greps the archives and can copy out the q and d files that has
that persons email address within the message? He mainly wants to get
some recent contacts and the body of a few messages. I'll start on
something tomorrow, but don't want to reinvent the wheel :)
