I'm trying to add a remote SMTP server from the admin panel and I'm trying to modify the PHP mail option. I am adding everythnig, I'm clicking on the "Edit settings" button it shows that it ios saved, but after a page refresh the changes are lost. I also tried to modify the SMTP option and it worked like a charm on it. If it's not possible to change the "PHP mail" settings, can you give me a file to modify manually, as I want to send some mails, but I just can not do it right now, because of this issue!
