 This script can send MIME-mails with attachments. It uses the PHP mail-function.

 EXAMPLE:

 $mail = new MIMEMAIL("HTML");

 $mail->senderName = "sender name";
 $mail->senderMail = "sender@email";
 $mail->bcc = "bcc@email";

 $mail->subject = "This is the subject line";

 $mail->body = "Hello! This is a message for you.";   // OR: $mail->body = "path_to_file/filename";

 $mail->attachment[] = "path_to_file1/filename1";
 $mail->attachment[] = "path_to_file2/filename2";
 ...

 $mail->create();

 $mail->send("recipient1@email");
 $mail->send("recipient2@email,recipient3@email,recipient4@email");
