*Edge for Private Cloud v4.18.01*

Edge automatically sends emails in response to certain events as described in [Customizing Edge Email Templates](https://docs.apigee.com/private-cloud/v4.18.01/customizing-edge-email-templates).

Many of these emails contain a link. For example, when a new user is added to an organization,
the Edge UI sends the user an email containing a login URL in the form:

```
https://domain/login
```

The domain is determined automatically by Edge and is typically correct for the organization.
However, there is a chance that when the Edge UI is behind a load balancer that the automatically
generated domain name is incorrect. If so, you can use the conf_apigee_apigee.emails.hosturl property
to explicitly set the domain name portion of the generated URL.

To set the domain:

1. Open the ui.properties file in an editor. If the file does not exist, create it::  
   \> vi /opt/apigee/customer/application/ui.properties
2. Set conf_apigee_apigee.emails.hosturl. For example, set conf_apigee_apigee.emails.hosturl as:  
   conf_apigee_apigee.emails.hosturl="http://myCo.com"
3. Save your changes.
4. Make sure the properties file is owned by the 'apigee' user:  
   \> chown apigee:apigee /opt/apigee/customer/application/ui.properties
5. Restart the Edge UI:  
   \> /opt/apigee/apigee-service/bin/apigee-service edge-ui restart
