Managing Mail Domain Keys
H-Sphere 3.3 introduces the DomainKeys antispam technology: a domain-level authentication framework for e-mail by using public-key technology and DNS to prove the provenance and contents of an e-mail message. It is an analog of S/MIME signing and verification at the mail service level. Made via generation of public/private key pair, where public key posted as a TXT DNS record, while private key is stored in a pre-defined location on a mail server.
To enable and configure Mail Domain Keys for a mail domain:
- Go to the Mail Info menu and select a domain from the drop-down list.
- To enable DomainKeys for the domain, click the Enable icon next to the Mail Domain Keys Manager field.
- Click the Edit Mail Domain Keys icon next to the Mail Domain Keys Manager field.
- On the page that appears, set the mail domain keys preferences into one of the three states: Bad Error, Soft Error, or Ignore.
If you wish to reset your changes, click Restore Defaults.
- To apply these settings to antispam settings for all mail resources, click the Set button. Note that this will override individual mail domain keys settings for mail resources.
- Click Submit to apply changes.
To set greylisting parameters for a mailbox:
- On the Mail Manager page for a mail domain, find and click a required mail resource from the e-mail list.
- In the Edit E-Mail form, make sure the Mail Domain Keys box is checked. Click Submit to return to Mail Manager.
- The Edit Mail Domain Keys icon will appear next to the mail resource under the Resource Included column. Click this icon and configure the greylisting parameters as described above.
