Setting the hostname for links in generated emails

Edge automatically sends emails in response to certain events as described in Customizing Edge email templates.

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

https://domain/edge
https://domain/createpassword/token

The domain is determined automatically by the New Edge UI and is typically correct for the organization. However, when the New Edge UI is behind a load balancer, the automatically generated domain name might not match the external load balancer hostname. If so, you can use the conf_apigee_apigee.emails.hosturl property to explicitly set the base URL of the generated links.

To set the hostname:

Open the management-ui.properties file in an editor. If the file does not exist, create it:
```
vi /opt/apigee/customer/application/management-ui.properties
```

Set conf_apigee_apigee.emails.hosturl. For example:

conf_apigee_apigee.emails.hosturl="http://myCo.com"

Save your changes.

Make sure the properties file is owned by the apigee user:

chown apigee:apigee /opt/apigee/customer/application/management-ui.properties

Restart the New Edge UI:

/opt/apigee/apigee-service/bin/apigee-service edge-management-ui restart
