is rumored to have said:
I know this doesn't look professional, but the question from the team
member does this contravene any rules or best practices.
list-manage.com
This domain does not have any A records.
It has a single MX record pointed at:
mail.admin.mailchimp.com
That hostname exists, but it doesn't have an A RECORD.
It in turn has just a single MX Record.
inbound-mx1.mailchimpapp.net
Kind of a strange MX delegation.. I assume to avoid CNAME's
Avoid CNAMEs isn't the rule. The rule is that the name resolved by a MX
MUST be a primary hostname, i.e. it MUST have an A record.
So this isn't just 'strange,' it simply should not work.
But it does seem very strange. Comments anyone? I didn't have an
answer for him..
