I have a game on Play Store which has around 3 million downloads to date. In-app purchases are being frequently stolen using either Lucky Patcher or other similar software. I need someone to find two more hacking programs similar to Lucky Patcher, and test them on my app. You will need to supply me with the exact GMT time of the transactions, as well as a written report. The report should detail as much information as possible about the developers of this software.

Hello. We are currently looking for someone who can design / configure and setup a mail scanning solution. What it must do is provide between 2 or 3 MX servers and these will scan emails for Spam and Viruses before they reach the end user. For example the client would setup the MX records to our solution and then once the customers domain was added to our solution it would scan the emails and then release them onto the customers email server if all in order. It must have a few features which include: 1) It must support scanning by domain and not by mail box. 2) It must be redundant over at least 2 servers but more likely 3. 3) It must be efficient at spam detection and virus scanning. 4) There needs to be a way a customer can login and access / whitelist spam etc. There is a more detailed list of requirements but what I am looking for is someone to come to me with a solution which I can then look into in more detail. If the suggested solution works we will then approve the job to build and test it.
