Monks, I'm trying to send via Cc with sendmail. The first recipient receives the email and the headers look correct with a CC, but the email never makes it to the copied address.

 open (MAIL, "|$sendmail $recipient") || die "Can't open $mailprog!\n"
+;
   print MAIL "From: Return Address <$return_email>\n";
   print MAIL "Reply-to: $return\n";
   print MAIL "To: $recipient\n";
   
    if ($email2) {
    print MAIL "Cc: $email2\n";
    }
    
   print MAIL "Subject: Test!\n\n";

Is this even possible?
