| # MX record with CRD source
 | |
| 
 | |
| You can create and manage MX records with the help of [CRD source](../sources/crd.md)
 | |
| and `DNSEndpoint` CRD. Currently, this feature is only supported by `aws`, `azure`, `google` and `digitalocean` providers.
 | |
| 
 | |
| In order to start managing MX records you need to set the `--managed-record-types=MX` flag.
 | |
| 
 | |
| ```console
 | |
| external-dns --source crd --provider {aws|azure|google|digitalocean} --managed-record-types=A --managed-record-types=CNAME --managed-record-types=MX
 | |
| ```
 | |
| 
 | |
| Targets within the CRD need to be specified according to the RFC 1034 (section 3.6.1). Below is an example of
 | |
| `example.com` DNS MX record which specifies two separate targets with distinct priorities.
 | |
| 
 | |
| ```yaml
 | |
| apiVersion: externaldns.k8s.io/v1alpha1
 | |
| kind: DNSEndpoint
 | |
| metadata:
 | |
|   name: examplemxrecord
 | |
| spec:
 | |
|   endpoints:
 | |
|     - dnsName: example.com
 | |
|       recordTTL: 180
 | |
|       recordType: MX
 | |
|       targets:
 | |
|         - 10 mailhost1.example.com
 | |
|         - 20 mailhost2.example.com
 | |
| ```
