mail() not functioning properly?

[128kb_com]

I'v compiled php4.3.0RC for my linux box and for my OSX box. The problem is, the mail() function keeps displaying an error message for no apparent reason.

I try a basic mail() from the CLI:
$ php -r 'mail("[e-mail]", "subject", "test") or die ("nope");'

and it returns:
"Recipient names must be specified
nope"

then I get my prompt back. The same happens from a script. This is only happening on my linux box with 4.3.0RC but not my OSX box with same version - similar build.

If I'm correct, the mail function isn't reconizing the recipients properly. Can anyone help me out?

Nevermind, I changed the sendmail_path in my php.ini to read:

sendmail_path=/usr/sbin/sendmail -oi -t

(I had to add the -oi t)
