Last month I ran into a guy on the dmarc list who complained that his
server returns NOTIMP in response to queries for SPF records ("because
it doesn't implement them") and clients were doing odd things. But
it's been a long time since I've run into anyone else like that, so I
agree, it's not an issue.
In case it wasn't clear, this is an authoritative server.
A authoritative server should be returning NOERROR / NXDOMAIN not
NOTIMP
Yes, we all know that. My point, which I would have thought was obvious,
was that it's been a long time since I've run into anyone whose server was
broken like that. As I said, it's not an issue.
R's,
John
