Sounds like it.

Okay, so next question.. might be totally out of topic for SA.. How can I
make
the front-end mail server know if a email exists on the backend server..
Example.. I use qmail on my front-end.. I don't like receiving tons of
invalid
emails just to turn around and attempt to deliver bounces that could
possibly
be going to honeypots or servers that don't take mail etc.. I solved
this on
my own domain by using a smtp vrfy script that checks against my backend
mail
server.. but since the other domains don't have mailboxes on my back-end
server
and is only setup to relay their mail, it blindly accepts EVERYTHING for
them..
any suggestions?
Thanks, Billy
Are you asking how to prevent backscatter?

If so, you'll need to look at your MTA.
