As others have mentioned, this is sendmail trying to notify biff that
the user has new mail but you aren't running biff.  To stop it, add
the following lines to your sendmail.mc file, rebuild sendmail.cf and
restart sendmail:

dnl Disable biff notification
define(`LOCAL_MAILER_ARGS', `mail.local -Bl')
