php with .procmailrc

I'm trying to set up .procmailrc to capture emails sent out. The .procmailrc file should filter the emails to a php program if the email is not deliverable. The php program works if I pass the variables directly to it but the .procamilrc doesn't seem to pass the email to the php program. .procmailrc -----> :0 bc * ^Subject:.* | /home/httpd/capture/capture.php Any help would be greatful. Thanks. Derrick
