Use this interface to identify problems with your server's mail-related DNS records. The system uses these records to verify that other servers can trust it as a sender.
This section of the interface displays the following information:
Mail HELO — The server's HELO configuration.
The Mail HELO information appears if the
This section allows you to manage the server's Domain Keys Identified Mail (DKIM) record. DKIM verifies the sender and the integrity of a message. In addition, it allows an email system to prove that spammers did not alter an incoming message while in transit. DKIM also verifies that the messages your server receives come from the specified domain.
If any problems exist with the current record, this section displays the properly-configured DKIM record values in the Suggested "DKIM" (TXT) Record section. It also allows you to copy the Name and Value records that the system provides in the Suggested "DKIM" (TXT) Record section.
Download the Private Key — Retrieve the suggested private key. The system directs you to the Download the Private DKIM Key interface.
Exposing your private DKIM key is a security risk. If others obtain your private DKIM key, they could sign emails and impersonate you as a sender. Make certain that you only provide your private DKIM key to a trusted user.
If you install the DSO PHP handler without ModRuid2 or MPM ITK, and you enable DKIM, emails that you send will display
To add these fields to the email headers, contact your hosting provider and request that they add the missing fields via the following PHP script:
This section allows you to manage your domain's Sender Policy Framework (SPF) record. SPF verifies that messages sent from your domain originate from an approved sender.
If any problems exist with the current record, a correct SPF record configuration will appear in the Suggested "SPF" (TXT) Record section. This section also allows you to perform the following actions:
Copy — Copy the Name and Value records that the system provides in the Suggested "SPF" (TXT) Record section. If you do not possess the authority to edit your record, you can provide this information to the person responsible for the listed nameservers to fix it.
The View option allows you to modify the record displayed in the Value field:
View — Modify the Value field's displayed record:
Customize — Modify the suggested SPF record. This directs you to the Customize an SPF Record interface.
Use this interface to customize the system's recommended SPF record for a domain. The interface displays the domain's current SPF name and value in the Current "SPF" (TXT) Record section, if one exists, and the system's recommendations in the Suggested "SPF" (TXT) Record section.
You can configure the following settings:
This section allows you to define the hosts or MX servers allowed to send mail from your domain.
Additional hosts that the system allows to send mail from your domain. The system automatically includes the primary mail exchanger and other servers for which you created an MX record.
|Additional MX Servers|
The MX entries allowed to send mail from your domain.
This section allows you to add additional IP Address blocks to the domain's SPF record. The system automatically includes your server's main IPv4 or IPv6 addresses in these lists.
You can use CIDR notation (for example
This section allows you to modify additional SPF record settings.
|Include List (INCLUDE)|
Additional domains to include in your SPF settings. Use this setting, for example, when you send email through another service, such as Mailchimp ®.
|Exclude All Other Hosts ("-all" Entry)|
Exclude any hosts that the other SPF mechanisms do not allow.
This section displays what the updated SPF record will look like, based on its current modifications. Click Install a Customized SPF Record to install the new record.
If you do not possess the authority to update a domain's SPF record, the system disables the Install a Customized SPF Record option. Use the Copy option to copy the provided record in the text box to your computer's clipboard. Email this information to the person responsible for the nameservers and request that they update the SPF record on the authoritative nameserver.
This section allows you to view and verify a domain's current pointer record (PTR). A PTR record is a DNS record that resolves an IP address to a domain or host name. The server uses this record to perform a reverse DNS (rDNS) lookup to retrieve the associated domain or host name. A PTR record requires an associated A record.
The interface provides information when a problem exists with this record. It also provides instructions for how to fix your PTR record.
