Fix Postfix mynetworks if IPv6 is disabled

Browse Source 
If a deployer sets disable_ipv6 = yes, we should ensure that the
mynetworks directive in /etc/postfix/main.cf contains only IPv4
addresses. The `newalias` command fails if IPv6 addresses appear
in mynetworks but IPv6 is disable system-wide.
