Basically you are nesting homedir/meta data inside the Maildir root. This is
where the errors stem from. Sieve scripts and index data should not
reside within same.

This is a bit overcomplicated. Try using a construct like:

 mail_location = maildir:~/Maildir

http://wiki2.dovecot.org/MailLocation/Maildir

This however requires home directories to be set accordingly in the User
Database:

> userdb {
>   args = /etc/passwd.dovecot
>   driver = passwd-file

http://wiki2.dovecot.org/AuthDatabase/Passwd

With the changes in place the nesting can be avoided by simplifying:

> plugin {
>   sieve = /mnt/user/Maildir/%u/.dovecot.sieve
>   sieve_dir = /mnt/user/Maildir/%u/

 sieve = ~/.dovecot.sieve
 sieve_dir = ~/sieve
