[Dovecot] Quotas not recalculating

[Kyle Brantley]

Hello all --

I have an interesting issue, where the quotas are refusing the 
recalculate for anyone on my server.

# doveadm quota get -u kyle at averageurl.com
Quota name                           Type    Value Limit %
storage=540672                       STORAGE     0     - 0
storage=540672                       MESSAGE     0     - 0
# doveadm quota recalc -u kyle at averageurl.com
# doveadm quota get -u kyle at averageurl.com
Quota name                           Type    Value Limit %
storage=540672                       STORAGE     0     - 0
storage=540672                       MESSAGE     0     - 0
# du -sh /var/mail/vhosts/averageurl.com/kyle
512M    /var/mail/vhosts/averageurl.com/kyle

The IMAP client (Thunderbird) state that the user has no quotas in place 
at all. Now, if I copy the maildirsize file from another user to this 
user account, the quotas display in the IMAP client. At this point, 
however, trying to recalc the quota does nothing.

Any help with this would be appreciated, config below...
