MX record for Subdomain

Hi,

 

We have a domain with BT. We wish to use a subdomain for a email elsewhere

 

So xyz.com is our main address

 

     email.xyz.com is to be used for email elsewhere

 

Is it possible to set up an MX record for a subdomain?

 

I have managed to set up the A record, but can't see how I would attribute the mx record to the subdomain and not the domain.


Thanks

Hi Wiggy42,

 

This will need to be added as follows.

 

Type - MX

Key   - @

Value - email.xyz.com

 

 

Plus your A record as follows.

 

Type  -  A

Key    -  email

Value  -  IP address of the new server.

 

This should work, if not please let me know.

 

Kind Regards,

Thank you

 

Is it possible to set up spf records for this subdomain without affecting the main domain?

I can confirm this is possible.

 

It is just a case of entering the "key" as "email" as follows.

 

Type  -  TXT

Key    -  email

Value  -  Spf record.

Hi Ian,

 

Thanks for that.

I have now been instructed that for email.xyz.com I need to set up two equal priority records

 

MX 10 abc.com

MX 10 EFG.com

 

How would I handle this so it is attributed to email.xyz.com and not xyz.com

 

I am also having issues adding a DKIM record due to the character limit to the field in the interface, I suspect I will need to call BT to sort this one.

Hi Wiggy42,

 

Please can you sent me a private message with the exact instructions, as well as the DKIM record as these can only be added on our side.
