I'm running qmailtoaster on a box that acts as a spam/virus filter for
our Exchange server.
Any message that is not rejected by the various tests on the toaster,
and that is addressed to an address on our domain, is forwarded to the
Exchange server.
There are no local mailboxes on the toaster outside of the default admin
accounts.
Currently messages forward on to the Exchange server are bounced by the
Exchange server if they don't match an account on our domain. Many such
messages are designed to bounce spam off of the server with a forged
'from' address.
I would like to configure the toaster to 5xx reject mail sent to
non-existant addresses on our domain during the initial SMTP
conversation with the toaster.
It's simple for me to export a list of valid addresses from our Windows
domain. Is there a place where I can put these addresses in
qmailtoaster so that a message sent to an address not on the list is 5xx
rejected by the toaster, not forwarded on?
Thanks.
Brent Gardner
