[Dovecot] Deleted / read mails show up as new on remote imap clients

[Andre Bischof]

Hi,

I've one problem:

Mails, which I already read or deleted via my IMAP client (Thunderbird) 
on the same machine running the server (it runs behind DynDNS on my 
local machine, thanks to http://mein.homelinux.com/wiki/mailserver/) 
show up again if I connect via IMAP from other client computers, i.e. my 
notebook (Thunderbird again).

As you can see from the config below I have /home/user/Maildir, not 
/var/mail - is that the problem? Or is that anything else, resulting in 
status from emails not being stored (or not being available remote) in 
the responding dovecot files (dovecot.index?).

Some month ago I migrated from Cyrus, and if I remember correct I had 
some problems with migrating subscriptions, stati and so on (one had to 
use a special script, sorry, it's been some time now) ;-) So maybe s.th. 
went wrong which could be the source of this problem? Just guessing ...

Ok, here's my config:
