Тема: cc:mail trivial DoS attack - self mailbombing.
--------------------------------------------------------------------------------
This seems to work on most cc:mail installations
Send mail to postmaster@[x.x.x.x] where x.x.x.x is the IP address of the
server.
In most cases, the machine will mailbomb itself into the ground
with undeliverable mail messages.
For bonus points, use a bogus, undeliverable sender envelope and watch
it crash even faster.
In some cases, postmaster@rDNS.name will have the same effect, depending
how badly setup the server is.
Script kiddies may like to have fun by using a sender envelope belonging
to someone else. One case I've seen resulted in the machine sending over
5800 "postmaster: No such user" errors for one message sent to it.
