| DomainKeys and Domain Keys Identified Mail |
This section provides information about configuring various system parameters to support the DomainKeys/DKIM feature. From the Connect main screen, navigate to Admin > System Configuration > System Parameters. Refer to the following table for more information about configuring system parameters.
| Name of the System Parameter | Location | Purpose |
|---|---|---|
| Selector for the receiving domain | Category: Mail SendingAccess Level: Internal | Use this system parameter to specify the receiver domain selector to use when e-mail signing is turned on. |
| Turn on signing by default at the conversation level | Category: Mail SendingAccess Level: Internal | Use this system parameter to determine whether signing is enabled or disabled by default when a new conversation is created. |
| Signing algorithm for outgoing email | Category: Mail SendingAccess Level: Internal | Use this system parameter to determine the signing algorithm for outgoing email. Connect supports the following signing algorithms: 0 - No Signing, 1 - DomainKeys-Simple, 2 - DomainKeys-nofws, 3 - DKIM-Simple |
| Private key for signing outgoing email | Category: Mail SendingAccess Level: Internal | Set the private key used for signing outgoing email. Outgoing e-mail is not signed unless a signing algorithm is specified. |
| Enable signing for outgoing email | Category: Mail SendingAccess Level: Internal | Use this system parameter to enable/disable signing for the outgoing email messages at the global level. This system parameter acts as a switch. No email is signed when this system parameter is set to false. |
Connect provides the ability to turn off signing at the conversation level. If signing is turned off at the conversation level, the outgoing e-mail messages are not signed even if signing is turned on for a receiver domain.
Follow these directions to sign outgoing email messages.
