the http code is 3xx. Instead of thinking at big things like DNS cache
poisioning, first make sure something under your nose is missed.
Say you are the hacker: you gain access to the real server, with privileges
high enough to change apache config and restart the daemon. What is the point
in redirecting users to your own server when you can gain access to user data
(webmail login and password, then mailbox content) without anybody noticing?
I think Franck has no idea what's going on, and he should really investigate,
gather evidence and technical facts before we continue to enumerate every kind
of possible compromise :/

In fact I do know what is going on ! some hackers grab login/passwd of
our users !
In the mean time we have completely reinstall the extranet from scratch
on a new machine, passwords changed , etc etc .
Now the webmail which is "untouched" will serve to try to trap the "vilain"
The "event" happen on every new scholar year ( september ) at this time
the "software" run to grab passwds of naive users.
we have time to prepare "something" as we know now which machine
is the target.
