Just had a thought (uh-oh). Could I accomplish my goal with the
following virtual_alias_maps and transport_maps setup?

virtual_alias_maps:

userdomain.tld userdomain1.tld userdomain2.tld
blahdomain.tld userdomain1.tld userdomain2.tld
testdomain.tld userdomain1.tld userdomain2.tld
...

transport_maps:

domain1.tld relay:[192.168.0.2]
domain2.tld relay:[192.168.0.3]

Where mx2 and mx3 are 192.168.0.2 and 192.168.0.3, respectively. mx1 is
Internet facing and its public IP is in the mx record for domain.tld...
