Hi,
you havematch from local for local action "local"
match from any for domain  action "local"
match from any auth for any action "relay"
in your config. So I think what you see is the expected behaviour, 
because sendmail did not authenticate and icloud.com is probably not in 
.
If you want unauthenticated local connections to be able to send mails 
to everyone, you need to add a match from local for any.

I hope this helps.
Best regards,
Matthias
