Did you "purged" the deleted mails for this user? On mdbox you must run "doveadm purge -u $USER" to whipe out any as deleted marked mails etc.

I use a nightly cronjob wor this.

Hello,
I am using dovecot with mdbox+sis and I notice an ever increasing disk space usage since I converted mailboxes from Maildir to mdboxes. I have checked with a user and while it actually uses only 65K, his mdbox files on disk are more than 6G. The backup of his mailbox is just 64K. Any suggestions ?
Below are some relevant commands:
[root@mail ~]# doveadm quota get -u test Quota name Type Value Limit % User quota STORAGE 10135 31457280 0 User quota MESSAGE 186 - 0
[root@mail ~]# du -k --max-depth=1 /mdboxes/test/ 220 /mdboxes/test/mailboxes 6029348 /mdboxes/test/storage 6029592 /mdboxes/test/
[root@mail ~]# doveadm purge -u test [root@mail ~]# du -k --max-depth=1 /mdboxes/test/ 220 /mdboxes/test/mailboxes 6029348 /mdboxes/test/storage 6029592 /mdboxes/test/
[root@mail ~]# doveadm backup -u test mdbox:/tmp/MDBOX_TEMP/ [root@mail ~]# du -k --max-depth=1 /tmp/MDBOX_TEMP/ 16 /tmp/MDBOX_TEMP/mailboxes 65540 /tmp/MDBOX_TEMP/storage 65568 /tmp/MDBOX_TEMP/
