Read email for all users within a domain via POP3

[David Franklin <da...@htk.co.uk>]

Email for a user can be read via POP3 using a URL of the
form pop3://<user>:<password>@localhost:110/INBOX

This requires a sender to refer to the target user as user@<domain> where
<domain> has been configured in config.xml via <servername/>, and for James
to have been configured with this user via adduser / telnet 4555

Is it possible to (a) configure James so that all email for any user can be
read with a single POP3 URL, and (b) without having to create each user
explicitly?  i.e. email senders can send email to <anyone>@somedomain and
an email consumer can read all of the emails that have been sent to that
domain (I think some SMTP servers (IIS) refer to this as a drop folder).

Thanks,
David
