Log emails

Hi,

Is there any way to log all emails send using "mail()" PHP function; I have PHP run as SuPHP. I have tried to put the below lines into php.ini, but that doesn't seems to work fine

; Add X-PHP-Originating-Script: that will include uid of the script followed by the filename
mail.add_x_header = On

; Log all mail() calls including the full path of the script, line #, to address and headers
mail.log = “/var/log/phpheader.log”

I have exim-4.69-29_cpanel_maildir and it isn't works with 11.28 stable and 11.30 release.

Please somebody helps!

Thank you.
