I can't see my email in the saved search -> Email -> Specific Recipients but still I receive emails? any idea why? and how to fix it? in the email subject mentioned (originally To: other emails)

Emails are being sent from your sandbox, by default, emails are sent to the user who requested the refresh.

how can I fix that

Setup > Company > Email Preferences > Email Options. Change the setting to 'Do not send emails' under sandbox options.

but that will stop all emails. I just want to stop it for one employee, others are ok to receive emails.
