Thanks for the thoughts, BritTim & TenFour. Much appreciated.
I know we have her main address (wife@domain.tld) set up as a "send as" address in gmail, but we might need to do that for various other
something@wife.domain.tld addresses too. I'll look into that.
(It would be so nice if simple forwarding just worked. Too bad spammers messed that up for everyone...)
