Hello all, we are still using a ISPConfig 3.1.15, a bit old, but the update is already planned. We now have a web page with a form. The sendmail parameter under /etc/php-fpm/php81-fpm.de/webxy.conf should be adjusted. Instead of php_admin_value[sendmail_path] = "/usr/sbin/sendmail -t -i -f webmaster@xyz" only php_admin_value[sendmail_path] = "/usr/sbin/sendmail -t -i" should be used. Thought I write the last in the individual php.ini settings in the ISPConfig Gui, after that the template of ISPConfig is applied and I have both the first and the second parameter in the config. Then I was of the opinion that the last thing parsed in a file wins. Wrong thought, the line php_admin_value[sendmail_path] = "/usr/sbin/sendmail -t -i" is ignored. What can be done? I wouldn't like to touch the template, because then the sendmail command doesn't work properly on other websites.
Not only a bit old, but also very insecure. Several serious security bugs have been resolved in 3.2+ and later. I think the php_admin_value use in the custom php.ini settings has been improved later on as well, so check if updating helps for you.
