my mail() doesn't work

[arastirici]

I use php5, qmail, apache2 and opensuse11.

I couldn't send a mail with mail() in php5.

I don't get any error as php

I get a mesage as below mail log
Oct 31 17:56:51 php qmail: 1257004611.252948 new msg 1958248
Oct 31 17:56:51 php qmail: 1257004611.252978 info msg 1958248: bytes 322 from <root@php> qp 4343 uid 0
Oct 31 17:56:51 php qmail: 1257004611.287998 end msg 1958248
Oct 31 18:06:59 php qmail: 1257005219.012135 status: exiting

And the mail didn't go.

How can I correct this problem?

if the problem is qmail, I wish to active sendmail.

How can I run sendmail on opensuse11?

my php ini;
[mail function]
; For Win32 only.
SMTP = localhost
smtp_port = 25

; For Win32 only.
;sendmail_from = me@example.com

; For Unix only. You may supply arguments as well (default: "sendmail -t -i").
sendmail_path = /var/qmail/bin/sendmail




thanks
