Hello, I want to ask for help with: I am working on creating a newsletter service. If I have a gmail address on my website to send the newsletter, I would like my own server to authenticated gmail email.
If the address is not authenticated, the message will arrive as follows: Gmail was unable to verify that the message was actually sent from x...@gmail.com. For other providers, this is shown as follows: XYZ - x...@gmail.com via s10.mailxmasterplus.net From: s9.mailxmasterplus.net Authenticator: s10.mailxmasterplus.net How and what do I need to include in my service to have mail authenticated by my own server? -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
