I owns a domin name call   .

Recently,  I got to create a subdomain   and maps to a mail hosting company (called  ABC.COM)
their mail hosting server is thepc.ABC.COM

The subdomain I create is  .

My plan is such that email sending to  can be collected at my mail hosting company at their server thepc.ABC.COM.     Therefore my email will be having the syntax of

My  DNS entry looks something like this :-

       mit.XYZ.COM        MX

Can I just end here?

or do you think I should also create a CNAME, so that my email system will work find?     MX    CNAME

Please advise.  is it a msut to add in that CNAME entry,  or need not   at all.

thank you.

    The MX entry tells the mail system that the Mail eXchanger for is - this means that any SMTP servers sending mail to will look this up and connect to, as you require.

    I CNAME record states that mit.XYZ.COM is an alias of (Canonical NAME).  Now this may be required if you are using as the server name in your mail clients, as your mail clients would need to connect to the ISP server to retrieve the mail - but they would not be looking for MX records when they perform the lookup.  However, if all your clients are set to look at to receive their email then this CNAME is not required.

    that should be a basic DNS entry for you to use.
