No. You _REJECT_. If it's a valid sender, that causes the sending
mailhost to generate a bounce. You don't accept the mail and then
generate a bounce yourself.
The difference is that the majority of such mail will come directly from
spammers and virus-infected hosts, which _won't_ generate a bounce to
the (faked) sender when you refuse to accept the mail.]
If you just reject it at SMTP time, then legitimate senders do get
bounces.
