So, the missing piece is probably my understanding of how multinet mail
works. This is all multinet magic.
For inbound mail, yes, I have to have an MX record for
Larry.frugalcomputing.com and Moe.frugalcomputing.com.
Multinet on Larry is aware of MOE and is routing the email back to my user
on Moe.
