The principle purpose of the secondary mx, in this case, is to accept

today, the primary purpose of secondary mxs is to receive spam.




Or, perhaps one wants more direct control over the how long you can be down

before things bounce policy. A secondary MX allows that. The fuse on the

sending spool is at the discretion of the person running the senders
mailserver.

The time limit on your secondary MX is, presumably, somewhat under your own

control.



There are other legitimate purposes as well.
