Extra parameter in sendmail_path creating problem

[rizwan6feb]

I having problem in sending email from my server.

On using the following statement

echo ini_get("sendmail_path");
 

I receive the following output
/usr/sbin/sendmail -t -i -f [e-mail]

Which looks strange to me. My administrator says there is only "/usr/sbin/sendmail -t -i" written in the php.ini file against sendmail_path, so why is that variable modified automatically?

Running scripts from command line (as root) works, but no email is sent when i run the script from my browser
