mail problems - phpinfo information

I have been having all kinds of problems with the mail() function in PHP. I realize that there are problems inheritly, but I think I am still trying to track down the problem. My latest theory is that PHP isn't set up to work with the right mailing program. I know that our system is supposed to be using qmail that actually sits on a different server, but I found interesting information in phpinfo that is making me wonder if a local sendmail is handling the requests instead. Here are the things I am finding in phpinfo: sendmail_from no value no value sendmail_path /usr/sbin/sendmail -t -i /usr/sbin/sendmail -t -i SMTP localhost localhost smtp_port 25 25 Path to sendmail /usr/sbin/sendmail -t -i Enviornment MAIL /var/mail/kpratt (what does this one do?) With all of the above refering to sendmail, is there anyway that my mail() can actually be using qmail? Thanks!
