mail with php under linux

[Anon]

When i try to send a mail, i test the value of mail and the result is false, so the mail is not sent. WHY???

My code:

<?
if(mail("[e-mail]","je teste","ca marche ou pas"))
echo "OK";
else echo "pb";
?>

My php.ini:

[mail function]
SMTP = localhost ;for win32 only
sendmail_from = [e-mail] ;for win32 only
sendmail_path = usr/sbin/sendmail

PLEAS HELP ME!!!

In linux, you have to configure sendmail or exim or whatever program you use to send your mail out in the right way. I use exim.

You can test whether it works by trying to send a mail from the command line in linux ... just try mail [e-mail] and see what happens...
