That should be OK assuming as Dimitri Maziuk says you have
"inet_protocols = ipv4" in your postfix config (or the
equivalent for your MTA).

However, I note the domain doesn't have an MX. That should be OK as it
does have an A, but since plus.com is apparently misbehaving, we have no
clue as to what they are looking at, and adding an MX may help.
