What is happening is that spammers/viruses are sending messages to invalid
usernames at your domain and Your Postmaster Account is sending back an NDR.
But! the senders account is also invalid, So the NDR gets bounced back to
you.
You can either add these senders to your filter list and/or add the
recieving addresses to an Email Enabled Distribution Group with No Mailbox,
so the messages get dumped into hyper space with out any NDRs.
Also consider Spam Filtering software, some of these can deny messages to
invalid users.

Remove the kNOT to reply.
But it is best to share it with the group.
