Description

Hi,

What I propose is to extend the Mail interface in the Mailet SDK with the
following methods:

Object getAttribute(String name);
Iterator getAttributeNames();
void removeAttribute(String name);
void setAttribute(String name, Object object);

The reason is that it will allow Mailet developers to pass, Mail processing
information between different Mailets which are related to the particular Mail
in question and not the common context for the Mailets. If you now register
such mail related attributes in the MailetContext, you will get yourself into
trouble when several Mails are processed in different threads by different
Mailets.

The Mail object actually acts as a sort of Session object, but a developer
cannot register anything on this Session.

This change will also put the Mailet api more in line with the Servlet api,
which allows setting of attributes on bothe the ServletContext and the
HttpSession.

Regards
Søren

P.S. I will be implementing this, so I will be happy to contribute, if this
proposal gets approved.
