Check hotmail inbox plus a specific folder every half hour for emails coming from a specific email address. then upload .zip attachements to an FTP website.

I need the software to check our hotmail account on a regular basis example every half hour (please add a setting to change the interval value). and search both inbox and another folder(MCKCatalogue) for specific emails coming from (certainEmailAddress) then upload any .ZIP attachements to an FTP website. - It must be written in VB.NET 2005 - .NET native code preferred but if you need to use any DLL it must be a free license for commercial use.
