Question about mail()

Hi php-general,


I have a question about the mail function. In the API I saw, that when
running on linux, I just need the binary sendmail, usually located on
/usr/sbin. Windows users need a running mail-server.
I have php working on a linux machine. Why do I need to have postfix running then to make it work? I posted
before, because no mails were sent. I had the sendmail-binary
(postfix) installed, but postfix was not running.
Maybe someone can explain it to me...

SvT
