When there is a need to configure domain redirection to another host or mail server, the Kerio Connect forwarding can be set up.
This article describes the process to follow to forward messages to another server if the recipient is not from your domain.
- Log in to Kerio Connect Webadmin.
- Double-click on a Domain.
- Go to the Forwarding tab.
- Enable the option "If the recipient was not found in this domain, forward the message to another host."
- Enter the information requested in the Forward to: and Port: boxes.
- Set the Delivery options. Messages can be forwarded immediately, by the scheduler, or by the Extended Turn (ETRN) command. The default option is online - deliver immediately.
- (Optional) Select the "Don't forward such message (prevent loops in multiple server scenarios)" option to disable the forwarding of messages sent to domain alias addresses.
Note: To forward messages, you can also create a message filter rule (Redirect to address option) on the server. For more information, please refer to Creating Outgoing Rules.
Confirmation and Final Considerations
- Any new messages sent to a recipient outside your domain are forwarded to the address you have specified.
- Forwarding the messages to the host is hard-coded. If there is a Delivered-To header in the email to be forwarded, it will take that into account. There is no way to customize this configuration.
- This all relates to the built-in DNS resolver that Kerio Connect features. With the built-in DNS resolver, Kerio is not able to process messages that have a malformed email address, and the behavior cannot be worked around.
- If the SMTP server requires authentication, you can configure the SMTP delivery rule.
