The easiest way is to add another mx record with higher precedence to your
domain pointing to your home machine and install qmail there, set
~/control/me and just copy over ~/control/rcpthosts from your original
server. Thats all. You don't need to change this setup when you're finished,
your home qmail will get all mail as loang as your primary server is down and
send it to your primary when it becomes availabel again.
The important thing here is that your domains are NOT in locals or
virtualdomains.
