mail problem

Hi,

           After configuring the netsaint properly mails are coming, but
too many mails are delivered even though there is no change in the
status of the host.  For example, the host 192.168.100.1 has been
stated  as down in the first mail is reported again in the second and so
on ( ie.  all the mails at an interval of 5 minutes alerting as the host
down) . Please provide me a solution where I should get a mail only on
the event of status change. Suppose a host,  which is already stated to
be  unreachable/down , comes up then a mail should be initiated
otherwise the message in the first mail holds good.

Thanks
Pramod
