I`ve setup a new server for PM220.127.116.11 and try to configure the mail-function (menu ADMIN->SETUP-->Email-Servers).
Using the PHPMAILER (SMTP) works fine. But when I try to use function Mail(PHP) , testing the eMail Server fails.
Postfix is installed and working fine (testet commands "mail" and "sendmail" from console).
I`m not very familiar with php and I want to identify the possible cause or configuration issue. So can anyone point me to the right direction to identify a misconfiguration ?
