Q about rejected emails (was: RE: [vps-mail] /dev/null in virtusertable on VPS2?

["Look at SomethingCool.com" <look@xxxxxxxxxxxxxxxxx>]

Ok, so I did this... And now when I send email to 
nosuchuser@xxxxxxxxxxxxxxxx My email client pops up a message telling me
that there is no such user found on somedomain.com.  Which is true.

This lead me to wonder if this could result in a denial of service to my
server, if some spammer sends thousands of spam messages to bogus users
on somedomain.com and my VPS2 server is sending this message back for
each bogus email...

On the VPS1, /dev/null in the virtmaps file doesn't have this behavior,
it seems to silently drop the bogus emails.

Your thoughts, folks?

Thanks,

Tim
