Notes on Forwarding
GoDaddy will largely forward email with DKIM signatures intacts. However, customers of GoDaddy's infrastructure are free to run their own configurations that can and do modify messages and break DKIM signatures.
When deploying DMARC, domain owners often find that email can flow through forwarders before arriving at a final destination.
Domain owners then wonder if the forwarder is capable of interoperating with DMARC.
This directory contains information on the capabilities of various email forwarders.
