I want you to test my domain AND IP for the possibility to use it to send spam emails. It is not enough to have the domain name in the sender field, obviously, but it must appear to be from my ip and my domain.
I will choose the most promising bid, will put the money to escrow, but pay it out only if you can hack my system.
If you want to play around a bit, in order to understand how much to bid, go to innup de.

We can do a full security audit of your server, not just testing for open relays ([url removed, login to view] isn't an open relay by the way). This price reflects a one-off system audit for one server.
