S= is the "physical size", W= is the "virtual size". quota=count / vsize calculations should be using the W= value, not the S= value.
I renamed all messages containing S= and W= values in a user's mailbox (Trash) which had the incorrect quota calculation, stripping these from the filenames to ensure they were not causing incorrect calculations.
Then, I deleted every single dovecot* file in the user's mailbox (all indexes and control files, including dovecot-uidlist):
root@server:~# find /mail/<username>/Maildir/ -type f -name 'dovecot*' -delete
Running
doveadm mailbox status -u <username> 'vsize' 'Trash'-still-, even after all this, returns a vsize calculation that is off by a factor of about two:root@server:~# du -bs /mail/<username>/Maildir/.Trash 7200481589 /mail/<username>/Maildir/.Trash root@server:~# doveadm mailbox status -u <username> 'vsize' 'Trash' Trash vsize=14584428026
(The user was not logged in during any of this testing)
I am at a bit of a loss at what is causing this issue now. I have tested against 2.3.13 and 2.3.14 now. Any chance I may have hit a bug in these versions?
It is worth mentioning that I have only encountered a small handful of users (out of about 100k) where the quota calculation is wildly incorrect. For the most part it appears to be right.

Hi!
Quota will count only virtual size of mails (and not directories) and that will likely never match with du -bs, which counts for things more than just the mail contents.
