disable reply if username is not available.

[codehaxor]

How do i set scalix to disable replying to the sender if the username is not found here in my server.

for example someone emails me@domain.com if me is not available scalix will send back to that sender that me@domain.com does not exist. How do i disable this feature since there are alot of spam coming in and it only clogs my mail queue

Thanks in advance.
