> Commons email is a simplifying wrapper around another API. It is also expected to be used in server environments.
> By default there are no connection timeouts set, this can (and does) cause threads to hang indefinitely. Since the goal of commons email is to simplify configuration, there should be a reasonable default value set. The default config should not risk a hanging a server. 
> This situation was easily produced using the gmail SMTP gateway. When > ~10 open connections exists the SMTP server starts resetting connections. Once in a while this will cause a thread to hang in IO wait indefinitely. The solution was to set the timeouts, but it is very easy to overlook the need to set this timeout, and natural to expect the wrapper class to handle such details.
> The snippets of code below belong in 1.3 Snapshot [as of 8/21/2010] org.apache.commons.mail.Email, they set a default of 1 minute timeout for connection and IO and update the javadocs.
