Hi friends,
On Debian Jessie, Postfix 2.11.3 and Spamassassin 3.4.0-6, I've just
setup an MX email backup server and now I realize that new spam come
from the MX backup server..
Is there any way to tell to reject any mail coming to the MX backup
server, if the primary server is up?
And again, many spam email came from a mine fake and nonexistent
"alias", for example:
on my server I guest i...@foo.org, and its alias: ali...@foo.org and
ali...@foo.org, and stop. The spam come from ali...@foo.org, that
doesn't exist, how I could reject and prevent to delivery from these
address, without compromise the backup server?
Many many thanks!
