Yes, but MX records for subdomains need to be configured using a separate DNS zone.


BinaryLane DNS does not currently support adding an MX record for a subdomain directly inside the parent domain's DNS zone. For example, you cannot add an MX record for mail.example.com.au directly on the example.com.au DNS records page.


To configure this, create the subdomain as its own DNS zone and delegate it from the parent zone.


Example

To add MX records for mail.example.com.au:

  1. Create a new DNS zone for mail.example.com.au.
  2. In the new mail.example.com.au DNS zone, add the MX record at @.

    For example:

    Name: @
    Type: MX
    Priority: 10
    Value: your mail provider's MX hostname
  3. In the parent example.com.au DNS zone, add NS records for mail pointing to BinaryLane's nameservers:

    mail NS ns1.binarylane.com.au
    mail NS ns2.binarylane.com.au
    mail NS ns3.binarylane.com.au


Once DNS propagation completes, public DNS resolvers will follow the delegation from example.com.au to the separate mail.example.com.au zone and use the MX records configured there.


Important note

Simply creating the separate subdomain DNS zone is not enough. The parent domain must also contain NS records delegating that subdomain, otherwise public DNS resolvers will not know to query the separate zone.


If you are trying to receive mail for the parent domain, such as user@example.com.au, add the MX record at @ in the parent domain's DNS zone instead.
