> search for "Catch all with sendmail" or something like that

Put this in your sendmail.mc and rebuild sendmail.cf
Be sure to have "unixuser" created on your local unix OS.

    define(`LUSER_RELAY', `local:unixuser')dnl


I used this approach, but you still spend resources scanning and delivering
this mail.
It can be costly on a system that get's bombarded with spam.
