Hello,

At the first, sorry for my englishJ

I have a problem with dovecot quota since i migrated from courier. Dovecot does not update the Maildirsize after expunge, and the user running out of his quota very quickly.

I checked, the file is deleted from the filesystem. If i delete the Maildirsize file, dovecot regenerate it with the correct datas when a new mail arrive.

Also tried to set mail_debug=yes, but it doesnt show anything in the log, when delete mails.

Im using NFS as homedirs, i tried to turn off the releated options in configuration, but didnt help.

Has anyone any idea how to fix this issue? Thank you!

Here is the output of dovecot -n:

# FROM users WHERE userid = '%u'

# Query to get a list of all usernames.
