dovecot - Apr 2021 - .IMAP locations

I have this account, /usr/home/me
To be able to admin websites, I created a folder /usr/home/me/www , 
containing my siteroot /usr/home/me/www/mysite.com

My dovecot.config:
mail_location = mbox:/home/%u:INBOX=/var/mail/%u

the actual mailfolder is /usr/home/me/mail , which I defined in my 
mailclient as 'mail/'

The issue now is that Dovecot is indexing my whole /usr/home/me/ folder, 
including the www folder, in which it also idexes every folder that is 
in /usr/home/me/www/mysite.com .
It puts in these folders an .imap folder that is containing the exact 
content of the folder it is put in. So my site takes double space by 
this Dovecot indexing.

To solve this issue, I defined my mail_location line as mail_location = 
mbox:/home/%u/mail:INBOX=/var/mail/%u
and removed the 'mail/' directive from my mail client.

For some reason this does not prevent Dovecot to index the subfolders of 
/usr/home/me/www/

- Do I have to remove all Dovecot related indexing files by hand to 
solve this and restart Dovecot service afterwards?
- Can you tell me how I can define the Dovecot index files location so 
that there will be no .imap folder created anymore in my 
/usr/home/me/www/ subfolder(s)?

Thanks for you help!
Elise

This is very unsafe, as you already noticed. Dovecot will iterate all folders it
can find, even if you are only opening mail/.

The .imap folder will not contain duplicate of your mails. It contains indexes.
These are not going to end up being same size as your mailbox.

You will have to restart dovecot.

Once you fix your mbox to point to correct location, they stop appearing.
