Baboon: Metaname is the only registrar I've used over the years, out of about a dozen, that has a different convention for inputting zone records. And no email or web provider I've ever used has handed out their DNS record info in the format Metaname insists upon.
They follow RFC1035 which is actually _the_ standard... https://datatracker.ietf.org/doc/html/rfc1035
This same standard is in-use by DNS servers (such as Bind, which they likely use for their DNS server). Most sites automatically add the trailing dot as stated above but Metaname also do make this clear on their DNS management page:
Names that are fully-qualified such as www.meowied.nz. or ghs.google.com. should have a trailing dot
