SPAMPROBLEM: Mailaddresses (FamName@xyz.ch, PreName@xyz.ch, UserName@xyz.ch)

Hi Folks,

My Name: Michael Bosshard,

UserName: mbo

Domain: xyz.ch (whatever)

Mailaddress: m.bosshard@xyz.ch (All set in names.nsf)

How can I tell my Domino 6.51-Server, that my emailaddress is ONLY m.bosshard@xyz.ch, and NOT michael@xyz.ch or mbo@xyz.ch. At this moment, Domino keeps delivering Messages sent to michael@xyz.ch… Does anyone know why?

Greez,

Michael
