How to configure and manage allowlist settings for trusted senders in 138 Enterprise Email?

To configure an allowlist in 138 Enterprise Email, access the admin console, navigate to Security or Anti-Spam settings, and add trusted sender domains or specific email addresses. This ensures emails from these sources bypass spam filters and deliver directly to inboxes, which is essential for internal systems, key partners, or verified clients to prevent missed communications. However, overuse can increase spam risks; regularly audit and update the list. For domain-based entries, verify senders have valid SPF, DKIM, or DMARC configurations—138 supports these sender authentication mechanisms to enhance security and prevent spoofing. Note: Allowlists only affect inbound filtering; outbound security depends on proper DNS records like SPF declarations for your domain. If configurations involve multiple systems or migrations, consult 138's official support for current parameters and guidance, as specific hostnames, record values, and validation steps must align with their provided details to avoid service disruptions.
