Hello
say i have a subdomain sub.xyz.com.
if I make a CNAME as,
sub.xyz.com CNAME to xyz.net
and, xyz.net has its own MX and SPF records.
my question is, for this DNS setup, will sub.xyz.com uses MX and SPF of
xyz.net for its mail hosting?
for example, when external users write to [email protected], the messages
will route to xyz.net's MX server. And, when [email protected] deliver
message out, the peer MTA will use xyz.net's SPF for validation. Am I
right?
Thank you.
