Whan my hide my email is set to forward to my Gmail account, nothing (or very little) gets through - nothing in spam in etc either. However when I set it to go to my work email. it does (albeit to spam). I checked with Gemini and it says there are some very fundamental issues that mean Gmail doesn't accept emails from hide my email, especially when they're automated type senders, and it recommends using a different email masking service (e.g. Duck Duck Go, or simple login). E.g. Gemini say the issue is "Gmail's strict gateway-level email authentication enforcement combined with how Apple’s "Hide My Email" relay system forwards messages".
Is this correct, is there no way to make HMyEmail and Gmail play nicely?
