To set up DKIM for MailEnable on YourDomain.com using Microsoft DNS, generate the public/private key pair in MailEnable, then create a TXT record in the Microsoft DNS console. In MailEnable, go to Domains > Properties > DKIM tab, configure key length (2048-bit recommended), and click “Configure” to generate the record.

Step 1: Generate DKIM Keys in MailEnable Open the MailEnable Administration Console. Navigate to Servers > Localhost > Extensions > Domain Keys (DKIM) to ensure it is enabled. Navigate to MailEnable Management > Messaging Manager > Post Offices > [PostOfficeName] > Domains. Right-click your domain (yourdomain.com) and select Properties. Select the DKIM tab and click Configure. Check Sign outgoing messages, set the selector name (e.g., mail1), and click Generate to create the keys. Copy the public key value generated for the TXT record.

Step 2: Add DNS Records in Microsoft DNS Log in to the Microsoft DNS management console for yourdomain.com. Create a new TXT record with the following details: Host/Name: [selector]._domainkey.yourdomain.com (Replace [selector] with the one used in MailEnable, e.g., mail1._domainkey.yourdomain.com). Value/Text: Paste the public key string copied from MailEnable (starts with v=DKIM1; p=…). Save the record and allow up to 48 hours for propagation, though it usually takes less than an hour.

Step 3: Verify and Test Use a tool like MXToolbox to verify the TXT record is correctly published.

Important Notes: Ensure that the private key generated in MailEnable is active in the domain properties. For better security, use a 2048-bit key.

It is highly recommendeded to pair this with an SPF record and DMARC policy for improved deliverability.
