Hi again.

A checkmark on "Stateless" will show recent stateless alerts that were
sent. A stateless boxDownWarning will be sent within 1 minute of a box
stopping ping response. A stateful alert, which must be resolved again,
will not be established until 4 minutes after the box stops responding
to ping. When the stateful alert is resolved, it disappears from the
status page.

Your alertengine.log indicates three different e-mails were sent to the
same address in this time period. Likely a `boxDownWarning`, `boxDown`
and later a `boxUp`.

If you didn't receive these e-mails, you need to check your e-mail
servers or spam folder - the problem is outside of NAV.
