why nginx requires authentication for smtp server?












0















according to the nginx documentation an http authetication service is mandatory for proxying a mail server. This is reasonable for your client who want to send emails through your server (465, 587) but why it is for recieving email from other mail servers (25)? (e.g gmail.com)

  • Nginx can perform the function of a Mail Proxy only. For "recieving email from other mail servers" you need an MTA such as Postfix.
