I'm trying to convince myself this is not my fault but I've been getting
several rejections over the past few months. My mail server has been
unmodified for a few years so I THINK it's not that, but sending mail to
(for example) bcs.hants.sch.uk results in:
(Host or domain name not found. Name service error for
name=bcs.hants.sch.uk type=MX: Host not found, try again)
The MX for the URI is:
bcs.hants.sch.uk.mail.protection.outlook.com
I use Unbound but it's set to resolve via cloudflare, opendns and
opennic. Could this, after several years, now be causing this problem?
