An email was sent to your alias {{ alias.email }} from its own mailbox {{ mailbox.email }}. SimpleLogin doesn't send this email back to your mailbox as it would be refused or hidden anyway by your email service. So no worries, there's nothing you need to do :). You can view this email here: {{ refused_email_url }} The email is automatically deleted in 7 days. Please let us know if you have any question. Best, SimpleLogin team.
