I have a situation I'm trying to work through that I'm not entirely sure how to solve.
Here's the situation:
I have a domain, let's say
sub.otherdomain.com, that I want to set up e-mail addresses on, and additionally set up an A record on. I don't own this domain, but the owners of the domain have set up a
CNAME record to point to one of my domains (let's say
My understanding is that setting up a
CNAME record will cause all record lookups for
sub.otherdomain.com to use the records defined on
customer.mydomain.com. This seems to work fine for the
A record I have set up, but the
MX records don't seem to be passing through the
In summary, the following records exist:
A xxx.xxx.xxx.xxx MX (mx details)
My assumption is that e-mails sent to email@example.com would use the
MX records from
customer.mydomain.com. Is this not the case?
