Thank you for your email.
We have been using XMail (www.xmailserver.org) for smtp and pop3, 
courier-imap for imap. This works for many years and we don't want to 
change. The only change we would like is to switch from courier-imap to 
dovecot. So configuration must be unchange: xmail for pop3 and smtp, 
dovecot for imap.
Unfortunately we are facing the problem I wrote about: after a user 
access mail box via web client (www.squirrel.org) he can not see emails 
any more via pop3. The reason is emails moved from 'new' to 'cur' 
although nothing done. Dovecot automatically moves. Currently with 
courier-imap, no matter we access via web mail or imap client (such as 
ThunderBird or Outlook) users can retrive emails via pop3. So my 
question is: does courier-imap behave abnormally or my dovecot
