Administrator Guide: Email Relay
Feature Overview
The email sending and receiving function expands the email channel, supporting both enterprise-owned email relays and Fanxiaoke email relays, enabling enterprises to send and receive emails compliantly and stably in CRM with their own domain names.
Usage Scenarios
When enterprises conduct overseas business or use internal email systems, they often require all external emails to be forwarded through the enterprise-specified email relay server to ensure security and compliance.
You can choose to forward emails through the enterprise-owned email relay or the Fanxiaoke email relay.

Domain Authentication
DKIM authentication for the domain is mandatory for the system to forward emails through the enterprise relay service or CRM. The system will regularly update the authentication status after completion.

Domain DKIM authentication is mandatory.
If Fanxiaoke IPs are added to the enterprise IP whitelist, domain DKIM authentication is not mandatory (DKIM authentication is still recommended for enhanced security).
- When an enterprise uses the Fanxiaoke email relay service:
Domain DKIM authentication is mandatory.
