             Project: Kylin
          Issue Type: Improvement
          Components: Tools, Build and Test
            Reporter: Jörg Weule

Dear Sirs,

I'm asking for an improvement to "commons-net" component "SMTP":

Unfortunetly sendMessageData returns a Writer where MimeMessage is able to writeTo(…) an OutputStream.
The MimeMessage has to writeTo(new CountOutputStream(new WriterOutputStream(smtpClient.sendMessageData(),"ISO-8859-1"))) using classes from commons-io. Unfortunetly there is no example to implement this and report the message size.

Why is there not convenience method to send a MimeMessage an returns the number of bytes send for mail statistics. This would do the job of writing to the writer and closing that writer:

  /* send the message */
  Writer w = smtpClient.sendMessageData();
  if ( w != null ) {
    w.write(...);
    w.close();
  }

Additionaly:

If we could have a DotTerminatedMessageOutputStream, we could write directly to the stream without the unneeded character transformation. The DotTerminatedMessageWriter is not really using the characters and I think this class can/should be implemented with bytes. When implementing a 
DotTerminatedMessageOutputStream, a character count would be fine to report the size of processed messages and to calculate performance data.

With kind regards

Jörg
