Note: As of Cascade CMS 8.13+, most system-generated emails will be sent via an external service (SendGrid). If you are not receiving emails from within the application, you may need to allow deliveries from
*.sendgrid.com at your email server to allow for deliveries. These emails will come from noreply@cascadecms.com. If you are using a proxy, Cascade CMS 8.16+ allows for configuring outbound connections for email as described in this article.Note: Since end users can link to any URL and port, the external link check could require other outbound ports for specific URLs. In general, you should be ok with only allowing port 80 and port 443.
