Reject vs. bounce

[Tim Boyer]

Apologies if this has been discussed ad infinitum before.  I've been running a
mailserver since 1996, but just heard about MailScanner Saturday, thanks to
Steve Swaney's excellent talk at the Ohio LinuxFest.

I've been using DNSBLs and a private blocklist with SpamAssassin, and ClamAV as
milters, so when I reject an email it's rejected, not bounced back to the
(99.999% bogus) 'From" address.  

I've heard and read that MailScanner has a 'bounce' option.  Is this what I
think it is - a bounce back to the 'From'?  Or is it a reject before the
connection's been dropped and the email accepted?
