Right, I have this set, yet it is still possible to have me send a mail
using Mutt with my From: address set as "host.my.domain".  This works great
for incompletely specified recipients and senders etc.  But I haven't
figured out how to incorporate myorigin to rewrite all addresses that match
a pattern to modify that (and only that) in the address.
