Kamaelia mail server

I have made a simple mail server for Kamaelia. Currently it can receive mail and store it but not forward it on. See /Sketches/RJL/SMTP/ in SVN.
The server's design follows the normal SimpleServer format except that each SMTPServer instance links itself to a shared QualityStorage component which handles saving messages (the 'quality' being that it confirms write-completition). A separate delivery component copies (hard links) messages into local mailboxes.
