[imp] newbee migrates from UW-imap to courier imap and screws up

[crane at ukonline.co.uk]

hi,
I installed UW-imap/horde/imp on redhat-9 as previous posts.
For compatability with my old emailserver, which I believe uses Maildir,
I removed  UW-imap and installed courier-imap-2.2.0

if 
  
[mick at scones mick]$ touch /home/mick/Maildir/new/testmail
 
[mick at scones mick]$ telnet 10.0.0.51 143
Trying 10.0.0.51...
Connected to 10.0.0.51.
Escape character is '^]'.
