Anyone have any experience with this, links to resources, or want to give me a price on setting it up? It's for email verification purposes.
 


Explain how does this apply for email verification. AFAIK, there are mods that run verification scripts. Why this hassle?
 
It is something needed by Gammadyne Mailer for a DKIM header. Here are the instructions from them:

1. Open a project and go to the Send/Details branch.

2. Check the "Use DKIM" box or the "Use DomainKeys" box.

3. Enter the Domain and Selector. The Selector can be anything
you wish, such as "default".

3. Click the "Generate" button. The Generate Window will
appear.

4. Go to the domain's DNS server management tool. Create a new
subdomain named "_domainkey".

5. Under the "_domainkey" subdomain, create a new TXT record.
The record name must be identical to the "Selector" field. The
record value must be identical to the "DNS Record Value" field
(as shown on the Generate Window).

6. Click "OK" to close the Generate window. The private key
will be copied into the project.

7. Click the "Test" button. If there is a problem, the DNS
record is probably not correct. The following website will help
test the DNS record:
