InternetAddress to =new InternetAddress("info@ddsds.uk");

MimeMessage message =new MimeMessage(s);

message.setFrom(from);

message.addRecipient(Message.RecipientType.TO, to);

BufferedReader streamIn =new BufferedReader(new FileReader(new File("/marketing/email.html")));

String htmltext;

String body="";

while ((htmltext= streamIn.readLine()) !=null){

body+=htmltext;

}

message.setSubject("Customer Enquiry");

message.setContent(body,"text/html");

Transport.send(message);
