C# Cleaning method/program for Outlook and Thunderbird

Hi, we need a method in to clean/remove all emails from: -sent emails -deleted objects -spam folder From the following email programs: -Outlook (2003, 2007 and 2010 support) -Thunderbird -Outlook Express -Windows 7 mail It needs to work under XP, Vista and Windows 7 on both 32- and 64-Bit. WE need an interface in C#. If you want then you can use another language such as C++ and create a DLL as long as you make it accessible from C# For each of those emails clients you need to provice us two methods like this: 1. public EmailInfo CheckStatus(); EmailInfo should be a class with the following properties: -sentMails_Number // how many emails are in the sent emails folder -sentMails_spaceUsed // an integer saying how much space is used by all emails in the sent box -deletedObjects_Number -deletedObjects_spaceUsed -spamFolder_Number -spamFolder_spaceUsed 2. public CleanResult CleanMails(boolean sentMails, boolean deteledObjects, boolean spamFolder); CleanResult should be an enum with the result value, which is one of the following: -Email_Client_not_installed -Error_while_cleaning -Cleaning_not_necessary -Cleaning_performed Everything needs to be executed directly without any dialogs and manual inputs. If an email application has more than one sent-/spam-/delete-box then the applicaiton needs to consider/clean all of them. Your method needs to be bug free and tested and we needd to receive the source code of course.
