On the Sites page, you can click the Advanced Configuration command for a site and then add additional domains which will be digitally signed using DKIM and/or DomainKeys.
Setting Up and Using DomainKeys
To add a domain
1. In the Domains Requiring Configuration group, click the Add Domain button.
2. In the dialog that appears, type in a new domain name.
3. When you are finished, click the OK button. The new domain name appears in the list and in the Domain field.
To auto populate the domains list
Click the Auto Populate button.
NOTE This causes ListManager to scan previous messages and find domains that you may wish to add.
To delete a domain
Click the domain, and then click the Delete button.
To create a selector for the domain
In the Selector box, type a selector.
To make the domain the default signing domain
(this will be used when there are no configured domains that match the "From" header domain)
Select Default Signing Domain.
To generate the public and private keys
1. Click the Bits drop-down list and choose a bit size.
NOTE This number determines the size (in bits) of the private key. You can choose one of five sizes: 512, 758, 1024, 1536 or 2048. The larger sizes offer greater security, but this is offset by a penalty in CPU performance. The current best practice size is 1024.
2. Click the Generate Key button. The private key and public key appear in the Private Key and Public Key boxes.
NOTE This procedure runs a program called openssl.exe in the background. You can also generate public and private keys by running openssl.exe outside of ListManager. If you have existing public and private keys and don't need to generate them in ListManager, select the Paste Your Key option, and then paste your keys into the appropriate boxes.
To save your settings for the domain
Click the Save Key button. This moves the domain name from the Domains Requiring Configuration list to the Configured Domains list.
To validate the key
Click the Validate Key button. NOTE For validation to be successful, you must first create and publish the domain TXT records.
When you are finished with the options on this page, click the Headers tab to choose headers to the include in the digital signature.
