How to purge mail stores?

sbudach

After two partially successful attempts to import my mailbox from Kopano, I noticed that the amount of storage used on the drive doesn't shrink, if I delete all messages from my mailbox in grommunio. Is there a means of purging deleted messages from a mail store, or do I have to delete the user and create a new one?

Delete the user completely and restart gromox or reboot.
Kopano2Grommunio.sh

gromi:~ # grommunio-admin user delete my@email.com --help
usage: grommunio-admin user delete [-h] [-k] [-y] userspec

positional arguments:
  userspec          User ID or name

optional arguments:
  -h, --help        show this help message and exit
  -k, --keep-files  Do not delete files on disk
  -y, --yes         Do not ask for confirmation

Really? There's no intended way of cleaning up a mail store other than to delete the user? What if I only wanted to delete, say 20k messages and keep the rest. Will the deleted messaged lurk in the mail store forever?

Currently not AFAIK. grommunio-admin was just extended with exmdb. But this doesn't include Data-Mangement yet to my knowledge.

Uhh… okay… I'll be counting on the "yet"-part then…

jengelh

/usr/libexec/gromox/cleaner -d /var/lib/gromox/user/X/Y (man cleaner)

crpb

jengelh /usr/libexec/gromox/cleaner -d /var/lib/gromox/user/X/Y (man cleaner)

Thanks. Always good to know.

sbudach Ha ha… too late… 😂 But thanks, this may will come handy over the next days, when I will be performing a couple of those migrations.

For the Migration-Tests I always deleted the Users.
With an LDAP as Backend it's just a matter of a couple of commands to destroy all users and recreate them with e.g. these vars/commands:

GROMOX_SVCS=$(systemctl list-unit-files |awk '/^gromox/ {ORS=""; print $1" "}')
USERLIST=$(grommunio-admin user list | awk '{print $2}' |grep -v -E '^admin$|^users$')
for user in $USERLIST; do grommunio-admin user delete --yes $user; done
systemctl restart ${GROMOX_SVCS}
grommunio-admin ldap downsync --complete --auto

Yes, but this is actually a home setup and I don't use LDAP for approx. 6 to 8 accounts. I was more concerned on a more general level, since this would also be good to know, of someone removed all their old messages and I would want to reclaim the space on the drive.
