"You have mail" problems...

[John W. Lemons III]

(If I'm being stupid, just slap my hand and put me to bed without my dinner)

"You have mail." appears every time I log into my server.  This would
normally be no big deal, except that the only mail message is the "Mail
system internal data" message.  Before QMail, this one message wouldn't set
off the "You have mail" message.  Do I have something mis-configured?

Thanks
John
