   Hello
   
   Is it possible to hide the ip from mail header for outgoing emails using the default Postfix and phpmail?
   
   Thank you

   Unless you know what you're doing, the easiest way is use Amazon SES 3rd party smtp servers and configure Postfix relay via Amazon SES. Amazon SES is only 1 of 2 3rd party smtp email services which proper strip the source origin email server's IP address to hide the server's IP.
   
   example Amazon AWS - Cloudflare - Postfix + Amazon SES + Cloudflare - Forward root mail safely-er

   I have the same issue that the header is leaking my server IP, leading to directly DDOS which is a nightmare.
   Beside of amazon SES, you can also use this add-on: Mailgun Integration [Paid] to send mail via API which doesn't include your IP in header or using a small VPS for sending mail via SMTP with mailcow.email | The mailserver suite with the 'moo' – + = or Mail-in-a-Box
