i'm running centos 6 server and my current php version is "PHP Version 5.3.29" so i need to update it to the latest version so could you please post the commands that i'm going to need to update it please ?
mail-header-patch=yes is set in the options.conf, but is not required with this php version.
To enable the X-Mail header, set mail.add_x_header to 1 in your php.ini
1.1.44
