Hi,

If the setup like this ..
ISP --> server1(abc.com)
-->server2 (xyz.com)
-->server3(sdf.com)

now both the server and isp running qmail . if the link between
server
and client broken than the ISP will hold the mail temporary and when
the link is up the isp will forward the mail . Is it possible ...how
to do that ?
....is there is any specific name / keyword (for google search :) for
this type of situation ?

Please help . Thanks .
