If your users have created any mailfilters, then these filters will get lost as they are written in maildrop syntax and not sieve as required by dovecot.
In 1.2.9 (Ubuntu 10.04) is directive in /etc/dovecot.conf
mail_location , which should be set to
mail_location = maildir:/var/vmail/%d/%n
Assuming i have to stay with mail_location = maildir:/var/vmail/%d/%n/Maildir as ISPC3 dovecot mail plugin is expecting this location ?
