dovecot - Feb 2015 - How to Delete an user and Purge attachements with a common directory mail_attachment_dir with SIS for all users.

Hello everybody,

    What is the best way to delete an user mailbox (ex: 
/var/mail/johndoe ) when all attachments  (for all users) are in a 
common directory with SIS deduplication (ex: mail_attachment_dir = 
/var/mail/attachments ) ?

Trying to delete user mailbox directory (rm) and do the command  : 
doveadm -v purge -u johndoe    leave  all johndoe's attachments orphelin.

Best regards,
TN

You should always expunge mailbox *before* deleting it, if you are using SIS.

# doveadm expunge -d -u johndoe mailbox '*' all
# rm -rf /var/mail/johndoe

Hi,

Many thanks for your reply. It's a *very important* addition actually.

There is lack of documentation on SIS. So I have done some experimenting and
found out that the command
# doveadm purge -u johndoe
*is mandatory*. Without this step attachements will stay in mail_attachment_dir
forever.

Man doveadm-purge(1) states "doveadm-purge - Remove messages with
refcount=0 from mdbox files", but actually it also removes attachments from
mail_attachment_dir.
