Set the length of your domain’s generated DKIM key
The default is **1024** |\n | dkim_selector | Explicitly set the value of the DKIM selector for the domain being created. If the domain key does not already exist, one will be created. The selector must be a valid atom per RFC2822. e.g valid value foobar, invalid value foo.bar https://datatracker.ietf.org/doc/html/rfc2822#section-3.2.4|\n | encrypt_incoming_message | Enable encrypting incoming messages for the given domain. This cannot be altered via API after being set for security purposes. Reach out to Support to disable if necessary. Default to false|\n | force_dkim_authority| If set to true, the domain will be the DKIM authority for itself even if the root domain is registered on the same mailgun account. If set to false, the domain will have the same DKIM authority as the root domain registered on the same mailgun account. Default to false. |\n | force_root_dkim_host | If set to true, the root domain will be the DKIM Host for the domain being created even if the root domain itself is not registered with Mailgun. The domain being created will still need to pass domain verification with valid spf records for the domain and valid DKIM record for the root domain. This does not effect the smtp mail-from host for the domain being created. The mail-from host will remain the domain name being created, not the root domain.|\n | wildcard | Determines whether the domain will accept email for sub-domains when sending messages. Default to false. |\n | pool_id | Requested IP Pool to be assigned to the domain at creation. |\n | ips | An optional, comma-separated list of IP addresses to be assigned to this domain. If not specified, all dedicated IP addresses on the account will be assigned. If the request cannot be fulfilled (e.g. a requested IP is not assigned to the account, etc), a 400 will be returned. |\n | spam_action | `disabled`, `block`, or `tag`
If `disabled`, no spam filtering will occur for inbound messages.
If `block`, inbound spam messages will not be delivered.
If `tag`, inbound messages will be tagged with a spam header. [Spam Filter](https://documentation.mailgun.com/en/latest/user_manual.html#um-spam-filter)
The default is `disabled`. |\n | smtp_password | Password for SMTP authentication |\n | use_automatic_sender_security | Enable Automatic Sender Security. This requires setting DNS CNAME entries for DKIM keys instead of a TXT record. Defaults to false. |\n | web_prefix | Sets your open, click and unsubscribe URLs domain name prefix. Links rewritten or added by Mailgun in your emails will look like ://./... Default to email |\n | web_scheme |Sets your open, click and unsubscribe URLs to use http or https. Value either `http` or `https`. Defaults to http. In order for https to work, you must have a valid cert created for your domain. See Domain Tracking for TLS cert generation. |\n\n Promise returns:\n\n ```JS\n {\n name: 'foobar.example.com',\n require_tls: false,\n skip_verification: false,\n state: 'unverified',\n wildcard: true,\n spam_action: 'tag',\n created_at: 2025-01-08T12:52:29.000Z,\n smtp_password: undefined,\n smtp_login: new Date('postmaster@foobar.example.com'),\n type: 'custom',\n receiving_dns_records: [\n {\n is_active: true,\n cached: [],\n priority: '10',\n record_type: 'MX',\n valid: 'unknown',\n value: 'dns_record_value'\n },\n ...\n ],\n sending_dns_records: [\n {\n is_active: false,\n cached: [],\n name: 'sending_dns_record_name',\n record_type: 'CNAME',\n valid: 'unknown',\n value: 'sending_dns_record_value'\n },\n ...\n ],\n id: '64a4291ebbe4ec7e1d78bc80',\n is_disabled: false,\n web_prefix: 'test',\n web_scheme: 'https',\n use_automatic_sender_security: true\n }\n ```\n\n- #### verify\n Verify the domains DNS records (includes A, CNAME, SPF, DKIM and MX records) to ensure the domain is ready and able to send\n\n [API Reference](https://documentation.mailgun.com/docs/mailgun/api-reference/send/mailgun/domains/put-v4-domains--name--verify)\n\n `mg.domains.verify(domainAddress)`\n\n Example:\n\n ```JS\n mg.domains.destroy('foobar.example.com')\n .then(data => console.log(data)) // logs response data\n .catch(err => console.error(err)); // logs any error\n ```\n\n Promise returns:\n\n ```JS\n {\n name: 'foobar.example.com',\n require_tls: false,\n skip_verification: false,\n state: 'active',\n wildcard: false,\n spam_action: 'tag',\n created_at: new Date('2017-10-05T14:55:20.000Z'),\n smtp_password: undefined,\n smtp_login: 'postmaster@foobar.example.com',\n type: 'custom',\n receiving_dns_records: [\n {\n is_active: true,\n cached: [],\n priority: '10',\n record_type: 'MX',\n valid: 'valid',\n value: 'receiving_dns_record_value'\n },\n ...\n ],\n sending_dns_records: [\n {\n is_active: true,\n cached: [],\n name: 'foobar.example.com',\n record_type: 'CNAME',\n valid: 'unknown',\n value: 'sending_dns_record_value'\n },\n ...\n ],\n id: '64a5880eere4eg7e1d85bc69',\n is_disabled: false,\n web_prefix: 'email',\n web_scheme: 'https',\n use_automatic_sender_security: true\n }\n ```\n\n\n- #### update\n Update domains configuration like smtp credentials, enable/disable automatic sender security, spam actions, wildcard, or tracking web scheme.\n\n [API Reference](https://documentation.mailgun.com/docs/mailgun/api-reference/send/mailgun/domains/put-v4-domains--name-)\n\n `mg.domains.update(domain, options)`\n\n Example:\n\n ```js\n mg.domains.update('foobar.example.com',{\n mailfrom_host: 'mailfrom_host_value',\n message_ttl: 20,\n smtp_password: 'smtp_password_value'\n spam_action: 'tag',\n use_automatic_sender_security: true\n web_scheme: 'http',\n web_prefix: 'web_prefix_value'\n wildcard: 'true',\n })\n .then(data => console.log(data)) // logs response data\n .catch(err => console.error(err)); // logs any error\n ```\n\n Update method accepts data object with next properties:\n\n | Property | Description |\n |:--------------|:----------------------------------------------------------------------------------------------------------------------------------------------|\n | mailfrom_host | The hostname to update to.

(template parameter is provided.) |\n | active | If this flag is set to yes, this version becomes active. |\n | headers | Key Value json dictionary of headers to be stored with the template.
