Daniel thank you for the advice, I have done this exact procedure to
clean up some space and I reduced the used space by more than 60% (huge
gain!). Yet it is still a mystery why this happened first place and more
important if it will occur again, time will tell. I have kept one
mailbox out of this procedure (the "live" size is 8,8G, the backup size
is less than 1GB) to do some testing or debugging if possible.
Another question I am not able to answer is if this procedure cleans up
potentialy orphaned attachments as I store them seperately for SiS to work.

There's probably a much better way to do this but sometimes a little
"brute force" helps.
Theoretical steps:
1. Stop all mail processes - both SMTP and IMAP.
2. Use "doveadm sync" to backup the user mailbox, e.g.,
doveadm backup -u user mdbox:/tmp/usermail
3. Verify /tmp/usermail looks reasonable
4. Move the user's mail store somewhere else, e.g. /tmp/useroldmail
5. Move /tmp/usermail to the user's mailstore
6. Verify file permissions are set correctly in the mailstore
7. Start the mail processes...and test.

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

[root@mail ~]# doveadm purge -u test
[root@mail ~]# du -k --max-depth=1 /mdboxes/test/

6029348 /mdboxes/test/storage

[root@mail ~]# doveadm backup -u test mdbox:/tmp/MDBOX_TEMP/
