title: Hide Sender IP address in Mail
body: <p>I'm currently trying to improve my emails discretion to prevent, as far as conveniently possible, a reader to tell (just by reading the headers) from where (which country, which type of device etc) I wrote the email.</p>
  
  <p>I'm sending mails through a provider's SMTP server using a domain name I own. I customized the message-id and host name and domain. Is there a way to hide the sender's IP address (and provider domain) or to make it appear similar everytime ?</p>
  
  <p>(Apart from using a VPN, which I think should work)</p>
