mail from www-data?

[joximu]

If fastcgi-php-suexec then the settings are in /var/www/fcgi/<domain>/php5(or 4?)/php.ini

if mod_php then you can add a php_admin_value in the apache config...

BUT: sendmail_from is only used in php/windows... (see php docu).

I think we have to change something in postfix so that outgoing mails are valid.
