I have Mail-in-a-Box running on a Linode VPS. Got assigned an IPv6 /64 subnet so I can meet Spamhaus’s requirements to get unblocked, and followed https://www.linode.com/docs/networking/linode-network/linux-static-ip-configuration/#ubuntu-18-04 to make the system use one of the new addresses. However, Mail-in-a-Box is still using the old IPv6 address, and even shows it when running
ip address shows both.
There are red status checks, but they are all related to DNS for domains for which I’m using external DNS. There are no red status checks for the main domain and the box’s subdomain.
I’m not really sure whether this is a Linode problem, a Mail-in-a-Box problem, or if I just screwed up somewhere. Regardless, any help would be appreciated.
