Correcting Mail Home, Maildir and Sieve folder locations

28 Jun 2020 · */ ; do mv "$i" mail; mkdir "$i"; mv mail "$i"; mv "$i"/.dovecot*


      I have Dovecot 2.3.7.2 on Ubuntu 20.04.
I just migrated the server from CentOS 8, and only migrated to the CentOS 8 machine a few months ago off of CentOS 7.
I am pasting doveconf -n at the bottom of this email.
Everything is working.
However, I'm trying to clean up warnings in the logs, and just discovered that I'm not managing home directories properly.
(c/f https://wiki.dovecot.org/VirtualUsers/Home)
This is in the logs:
...
Jun 28 06:09:50 mail.example.com dovecot: imap(email@example.com)<3786><fICEJCKpbfatQHg1>: Error: stat(/var/vmail/example.com/email@example.com/.dovecot.sieve/tmp) failed: Not a directory
Can I please get a sanity check?
To resolve, I've come up with a bash loop to create a home folder, and fix the existing structure for each mailbox on the system. 
I ran this for 1 of the domains on the system.
...
for i in */ ; do mv "$i" mail; mkdir "$i"; mv mail "$i"; mv "$i"/.dovecot* "$i"; done
Then, I would simply edit /etc/dovecot/conf.d/10-mail.conf so that it looks like this:
...
mail_home = /var/vmail/%d/%u
mail_location = maildir:/var/vmail/%d/%u/mail
To confirm, should all of the 'hidden' dovecot files be moved to the user's new home folder like I'm trying to do in the above script?
Or are there other files that I will need to move?
After running that loop above on a test server (don't worry, I would never do this in production without testing), one of the mailbox's home folder on the server looks like this:
...
total 56
drwxr-xr-x   4 vmail vmail  4096 Jun 28 06:19 .
drwx------   6 vmail vmail  4096 Jun 28 06:09 ..
-rw-------   1 vmail vmail    54 Jul  4  2019 .dovecot.lda-dupes
lrwxrwxrwx   1 vmail vmail    21 May 26  2016 .dovecot.sieve -> sieve/roundcube.sieve
-rw-------   1 vmail vmail     0 Oct 17  2016 .dovecot.sieve.log
-rw-------   1 vmail vmail   218 Jul  6  2019 .dovecot.svbin
drwx------ 277 vmail vmail 32768 Jun 28 06:19 mail
drwx------   3 vmail vmail  4096 Feb  2 17:31 sieve
... and connecting to that mailbox over Thunderbird seems to be working fine.
But I want to make sure I'm not missing anything.
Here is my doveconf -n, with identifying information snipped out:
...
