I just noticed that the table is searched by sender address and
@domain, so you'd need to specify @mymodeltalk.com and so on.

Yes, assuming that the IP addresses are correct.

The above is to receive mail. I thought you needed that, too,
but I may have misread your question.

If each domain is to have its own mail receiving address, yes.
However, Postfix is not really a multi-personality server. You can
fake it by setting "-o myhostname=mta-name-here" on the smtp and
smtpd process command lines. But when mail is not deliverable, then
(as required by RFC 5321) Postfix will send a non-delivery notification
with the null sender address, and that address will fly past your
sender_dependent_default_transport_maps.
Multiple MTA personalities require multiple Postfix instances.
