While that's necessary, it is typically not sufficient. One also
needs to make sure that that destination IP address is not listed
in "inet_interfaces".
In this case, an explicit setting of "inet_interfaces" to just the
public IP address of the machine would be required.
main.cf:
# Choose a non-loopback interface IP
#
inet_interfaces = 192.0.2.1
# Choose a name that is different from the name used in
# the SMTP 220 greeting banner or EHLO response of the
# non-Postfix loopback SMTP service.
#
myhostname = mail.example.com
