Hello, I'm trying to understand how to clean up old
dovecot.index.pvt.log files, which are used for per user private \Seen
flags. Running "doveadm purge" does not seem to remove them.
I have the following public namespace configured:
namespace public {
type = public
separator = /
prefix = Public/
inbox = no
hidden = no
mail_driver = mdbox
mail_path =
/data/mailstore/%{user|domain|lower}/mail_public/mdbox
mail_index_private_path = ~/mdbox/Public.index.pvt # Enable user private
\Seen flags
list = yes
subscriptions = no
# Allow users in the 'admin' group to have complete control over the
namespace
acl group=admin {
rights = lrwstipekxa
}
}
The problem is - if the admin deletes a public folder, the old
dovecot.index.pvt.log files forever remain in all of the users' home
mailbox directories, like tombstones.
I see two ways around it:
1. Attempt to store private index files in the original folder's mail
path, so when the folder is deleted, all files underneath it are also
deleted automatically:
mail_path = %{mail_directory}/Public.index.pvt/%{user|domain|lower}
However there appears to be no %{mail_directory} variable which would
expand to mdbox/mailboxes/<folder_name>/dbox-Mails/ and even if there
was one, with public folders, for every user subscribed to this folder,
there would be a user-specific directory just for the private index
file. This may not scale well with thousands of users.
2. Run a cron script to list all public folders and then compare
~/mdbox/Public.index.pvt directory of each user for stale private index
files which refer to non-existent folders. This can probably be done
efficiently with commands like find, awk and sed, but it feels a bit
cumbersome and arcane.
Can anyone suggest any other or better alternatives to solve this issue?
Thanks.
