Hmmmm.  Not sure what happened but there was a period when batchftp was
supposed to be working and it then broke again. :-(  Anyway, it should now
be working again.

This is because the real name of the machine is disabuse.demon.co.uk, and has
a CNAME (alias) in the DNS of ftp.demon.co.uk, this allow us to always have
a fixed name of ftp.demon.co.uk as the ftp server and point the alias at
another machine if we want at some stage in the future.

As for the email, well I'm not entirely sure myself, but it probably gets
re-written to <someuser>@disabuse.demon.co.uk after you've sent it to 
ftp@demon.co.uk, so that the actual ftp server itself receives the msg
locally and processes it.
