Hello, I have two questions about Email Signing with DKIM. 1. Does my domain need to support HTTPS (secure http) in order to use Email Signing and add a DKIM TXT record to my Domain. (my domain is HTTP, not HTTPS) 2. I have a domain web app that use the C# SmtpClient command to send an occasional email to a user. The app SmtpClient Host property is set to mxx.internetmailserver.net that is listed in my winhost website control panel. Do I need to set any properties on the C# SmtpClient to specify the DKIM encryption key? Are there any special SmtpClient Credential properties that need to be set to enable DKIM? PS. I have read the KB article on DKIM setup and understand it. I just doesn't answer my questions above. https://support.winhost.com/kb/a1599/email-authentication-through-spf-and-dkim.aspx Thanks for any help.
