I periodically export the mysql database with the encrypted user email
passwords and run it through John the Ripper, and it finds a few every
time.  So it will all depend on how good the password is.

Try it yourself with John http://www.openwall.com/passwords/unix.shtml;
it's not difficult.  If you use the big wordlists available at
http://www.openwall.com/passwords/wordlists/, you will be amazed at how
many passwords you can get.
