Hi guys, I believe that I already have the answer to this pretty basic
setup, but I just wanted to do a quick sanity check.
I'm setting up a backup MX, and for one of the domains that it will
relay to, it should do no filtering whatsoever as there is a Symantec
device in front of the primary. The device is configured with a
catch-all, and I have verified that no backscatter is generated when
sending to an invalid address, and the admin of that server wants to
review everything coming at him.
The backup should have the same filtering as the primary, since a lot of
spammers use it without every trying the primary, specifically because a
lot of people implement the backup without filtering.
