Secondary Sendmail Server Setup

Ok, as long as we are on sendmail, here is one that has bugged me for a
while.

What do I need to do to get mail sent to the secondary server while the
primary is unavailable over to the primary when it becomes available?
I have secondary working, it gets mail when primary is down, just not having
any luck finding how to get the mail off of the secondary.
