Re: Nginx mail proxy - ensure sender match authenticated user

Hello Maxim, Thank you for your answer. As you know, nginx does not send Auth command to backend server, so there's no way for the backend to know if the sender matches the authenticated account. I tried proxy_smtp_auth config but nginx send mail COMMAND to my server but it can not understand :(

Nginx mail proxy - ensure sender match authenticated user

Hello, I am a fan of nginx and I really like nginx mail proxy module. I'm having a problem between the authenticated account and the sender when using this module. For better understanding, please see my test below: root@nginx:~# telnet xx.xx.xx.xx 25 Trying xx.xx.xx.xx ... Connected to xx.xx.
