iRedMail: Daily user unknown entries from backup_sogo.sh

Posted on Sun 01 November 2020 in Tech

If you've been running iRedMail for a while, eventually you'll probably start seeing 'user unknown' events in your daily logs:

* Backup all users' data under /var/vmail/backup/sogo/2020/11/01

* Compress backup files.

This is because removal of an iRedMail user doesn't remove the corresponding SOGo user data. You can take care of this with sogo-tool:

root@server:/# sogo-tool remove abdulm@<domain.xyz> bent@<domain.xyz> brettr@<domain.xyz>

... etc. Once you're done, run the backup again to make sure you've got them all:

root@server:/# /bin/bash /var/vmail/backup/backup_sogo.sh
* Backup all users data under /var/vmail/backup/sogo/2020/11/01

* Compress backup files.
