How Our New Email Routing Works

Mon Mar 30 2026

Concept: Routing traffic to bypass residential/business IP blocks while maintaining local data sovereignty.

Sending Path (Outbound):

The IMAP client sends a message. Opening Synology MailPlus to the Internet intercepts the mail and tunnels it to the relay configured in Setting up AWS SES for Outbound Mail via Port 587 (TLS).
AWS signs the payload and delivers it from a high-reputation Amazon IP.

Receiving Path (Inbound):

An external reply queries the domain’s MX records.
Traffic is directed to the local public IP. The router forwards Port 25 directly to the NAS, bypassing AWS entirely.
