Zimbra by default send notification about number of emails in user inbox, total quota used,etc. First I configured admin on email@example.com and then I added example.com domain, and without any care I deleted mail.example.com domain. after that I added admin user with firstname.lastname@example.org account to zimbra by command line.
Now the notification aren't send to email@example.com. how can I enable it again and say zimbra send that notifications?
