Bounced e-mail returning back {Scanned}

[SW]

I've setup in MailScanner.conf the

Spam Action = bounce

which I thought should not cause them to come back to me:

--- The following addresses had permanent fatal errors --- etc.
(reason: 553  <No such user here)

I know spammers use fake e-mails so how do I prevent from getting these
messages back?

Thanks,

SW
