Could you elaborate more how the backup mx could be any more of a "spam

Spammers target backup mx on the premise that it usually lacks the
filtering of primary mx.

you can exploit this phenomena to reduce the spam load on your primary mailserver, by simply implementing the same filtering policy on your primary and backup mxes.


Jim Seymour explains it better that I could at

It's about two-thirds of the way down the page titled "When There's No> Point To A Secondary MX."
