We have installed php4.1.2 on iplanet 6.0 Webserver on a Solaris 8 OS.
The following config options were used:

./configure' '-enable-sysvshm=yes' '--enable-sysvsem=yes'
'--with-nsapi=/ecomm/iplanet/nes60/product' '--enable-libgcc'
Something really strange is happening. I have written this piece of code for sending e-mails.

########################################################

<?
$locat = "/usr/lib/sendmail";
$rk = "/ecomm/iplanet/nes60/product/docs/rohit/kkmail" ;

function doSending($emailFilename)
        {
        global $locat;
        echo "<br> locat ".$locat;
        echo "<br> emailfilename ".$emailFilename;
        unset($do);
        $do = "$locat -oi -t < $emailFilename 2>&1 ";
        echo " SYSTEM  " .$do;
        exec($do,$ret,$ret_var);
        echo "return_code " .$ret_var;
        echo "reta " .$ret[1];
        echo "retb " .$ret[2];
        echo "retc " .$ret[3];
        echo "retd " .$ret[4];
        echo "rete " .$ret[5];
        echo "retf " .$ret[6];
        }
doSending($rk);
?>

The code works very well when I have:
safe_mode=off in php.ini

But as soon as I put the following parameters in php.ini and restart the web-server:
safe_mode=on
safe_mode_exec_dir=/usr/lib 

(In /usr/lib where we have the sendmail executable).

The code displays this error on the php page:

locat /usr/lib/sendmail
emailfilename /ecomm/iplanet/nes60/product/docs/rohit/kkmailSYSTEM /usr/lib/sendmail -oi -t < /ecomm/iplanet/nes60/product/docs/rohit/kkmail 2>&1 return_code 67
reta <... User unknown
retb /ecomm/iplanet/nes60/product/docs/rohit/kkmail... Cannot mail directly to files
retc 2>&1... Unbalanced '>'
retd 2>&1... User unknown
rete /ecomm/iplanet/dead.letter... Saved message in /ecomm/iplanet/dead.letter
retf 

The php.ini file is like this:

########################################################

doc_root=/ecomm/iplanet/nes60/product/docs
safe_mode=on
safe_mode_exec_dir=/usr/lib
expose_php=Off

Any help would be deeply appreciated.

Thanks,
