I have Nginx setup for dynamic hosts (similar to Apache mass vhosts) and this is causing an issue with Postfix.
This is causing an issue for the server sending emails - Message-ID with no domain name.
In my server block I have server_name ~(?<domain>.+)$;
When Postfix sends an email, the message ID doesn’t show a FQDN, it shows @~(?<domain>.+)$, the same regex used for my server_name.
Does anyone know how to get Nginx/Postfix to play nicely together? The only thing I can think of is that Nginx isn’t passing the server_name properly.

Hi,
I believe Postfix is using the hostname that is passed to it by PHP. By default, the
fastcgi_params
file contains the following line:Adding the following line in your nginx config above
include fastcgi_params;
should set the$_SERVER['SERVER_NAME']
PHP variable to the actual domain name:Don’t forget to restart Nginx so that the changes take effect:
