have you checked your logcheck.conf file to see where logcheck is trying
to e-mail it's reports?  Have you ever received an e-mail from logcheck?
 If it's workign properly, you should.  I'm guessing logcheck is unable
to send it's e-mail, and kicks back the error to stdout, which cron
dutifully e-mail to you instead (that's what cron does to output from
the programs it runs)
