Additions to ipv6tables on linux don't include icmpv6.

Issue #168 resolved
Carl created an issue

The ip6tables configuration when you install iredmail and let it update them doesn’t include a blanket ACCEPT for ICMPv6. This stops IPv6 from working altogether as neighbour discovery requires ICMPv6. The following rule needs to be added.

-A INPUT -p ipv6-icmp -j ACCEPT

Blanket allowing ICMPv6 is not a security issue.
