When set to a value of 1, the
ipv6in option instructs Messaging Server to accept inbound IPv6 connections for all services provided that the host has at least one network interface configured for IPv6. Services specifically configured to listen on only IPv4 interfaces cannot also accept inbound IPv6 connections. When set to a value of 0, inbound IPv6 connections are not allowed.
Inbound IPv4 connections will always be permitted.
