I have an agreement with a friend of mine to serve as backup e-mail for
his company and vice-versa.
He has setup his MX records with my exchange mail server (IMS SMTP
installed) with a higher priority for delivery to
mine in case his is down.
I am now trying to figure out what I need to configure on my exchange
server to accept and hold mail for his
domain in my queue until his server comes back up.
If anyone could help me out with this, it would be appreciated.
