The "postmulti" command is not involved with IP addressing. Each
Postfix instance's master(8) process binds the listen endpoints of
"inet" services specified in master.cf at the addresses that are
specified either explicitly for each server ([address:]service),
or via "inet_interfaces" in main.cf.
Note also the setting of:
master_service_disable
which defaults to "inet" for freshly minted secondary instances.
You've not shared any configuration details (postconf -nf for
the primary and at least one secondary instance) so hard to
provide specific advice.
Basically, read the documentation more closely, and take time
to give each instance an explicit "inet_interfaces" setting
(not smtp_bind_address, you don't need that) and then enable
"inet" services.
