Each domain name added to OnePoundEmail has a specific DKIM key, so you'll need to complete this process for each domain you use.
Step 1: Log in to the DirectAdmin control panel with your OnePoundEmail service credentials.
Step 2: Select the domain you want to manage DKIM for in the top right drop-down menu.
Step 3: Navigate to the “Manage DNS” page from the navigation or search bar.
Step 4: Find the DKIM key, which is a TXT record that will start with “v=DKIM1”.
Step 5: Copy the full DKIM (excluding quotations, if your DNS provider autogenerates quotations like Cloudflare).
Step 6: Add the new record at your DNS management provider.
The type is always TXT. The host/hostname/name is “x._domainkey” and the target is the full key from Step 5.
