I also have a problem with Yahoo and i only send text/plain. I have SPF and dkim working. The email is triggered by a registration form and contains a base64 encoded hash in a link that must be clicked to confirm the email address. I already asked Yahoo about that and they answered I should wait and see if it gets better but after 10 days still the same. Regards, Clodoaldo > > Mark >
