fix: remove example users email ids from notifications

currently the system tries sending emails to all users that have
'thread_notify' enabled, including the default example emails that the
Administrator and Guest accounts have. this patch disables email
notifications for these accounts, and additionally tries to disable it
for any other user accounts with example emails
