today's bug preventing me from completing basic administrative tasks without doing backflips and wasting hours:
1. someone receives a message from iCloud Hide My Email
2. they forward it to you.
3. you receive it in Apple Mail, with the banner "This message was forwarded to you by Hide My Email" presumably because of the still-intact X-Icloud-Hme
4. you forward it elsewhere, carefully selecting the correct outbound address
5. Apple Mail ignores that address and just forwards it via iCloud
