Hi everyone,
I've got iRedMail with SOGo and MySQL as the backend.
I have daily / weekly / monthly backups of all db-s and files, but I need to restore just 3 contacts deleted a month ago by a user.
No sense in restoring everything.
Does anyone know where are contacts stored in SOGo with MySQL?

Thanks!
