Your message was undeliverable due to the following reason:

Your message could not be delivered because the destination computer was
not reachable within the allowed queue period. The amount of time
a message is queued before it is returned depends on local configura-
tion parameters.

Most likely there is a network problem that prevented delivery, but
it is also possible that the computer is turned off, or does not
have a mail system running right now.

Your message could not be delivered within 4 days:
Mail server 97.206.36.117 is not responding.

The following recipients could not receive this message:
