I would like to send emails with FMS16 to a few of my customers.
I use an @icloud.com email to send them.
Is it possible to use the iCloud.com smtp server?
I also need to respect the RFC 7208 (Sender policy framework).
Now I use the services of smtp2go.com for the smtp server.
The domains name checking the origin of the mail according the RFC 7208 reject my emails.
