I had a server (Debian) with ISPConfig, postfix and dovecot configured.
Accidentally i changed permissions on all my file system (chown root:users / -R).
After restoring permissions for postfix and some other essential services (i've mo nitored errors on /var/log/syslog) everything was fine. But later I realized, that new mails are now delivering to /var/mail/user_name instead of /home/www/web##/user/web##_user_name/mail/.imap/
None of config files was changed, so i think that incorrect permissions on some files is the reason for it. Ofcourse only new mails are visible now via imap.
I want at least to import all my old mail to new location. And ofcource will be better to restore old behavior (delivering mails to /home/www/bla-bla...).

what else can help?
