Dead email - how can I stop?

Im getting hundreds of dead emails a day they are sending to non existant people in my domian so they all end up dead.

how can I configure it so that before we accept the message for delivery

that the the server checks the Domino directory and if the name is not there -refuse it !

Subject: Configure it in a server configuration document

“Router/SMTP” tab, “Restrictions and Controls” tab, “SMTP Inbound Controls” tab, thenin section “Inbound Intended Repcipients Controls”, set

“Verify that local domain recipients exist in the Domino Directory:” to “Enabled”.

Bingo. No more dead mails.

Subject: That works for almost everything but…

Recipient user name xxxxx (xxxxx@xxxxx.com) not unique. Several matches found in Domino Directory
