Authentication and relay behaviour in email forwarding
Namecheap Forwarding accepts mail for a domain and relays it to the user's actual mailbox provider. This relay step introduces authentication challenges: when a forwarded message arrives at the final mailbox, it has passed through Namecheap's infrastructure, which may alter headers or fail SPF or DKIM verification if the relay address is not covered by the domain's published records. Filtering systems downgrade or reject forwarded mail that fails authentication, particularly if the domain publishes strict DMARC policy. Domain owners using Namecheap Forwarding should ensure their SPF record explicitly permits the forwarding relay, and should test forwarded mail delivery to external recipients before relying on the service for mission-critical communications.
