The project will be a prototype and will be integrated into a complete system at a later date.? The primary focus of this project is to produce a dll which can be integrated at a later date, however, for testing purposes it may be necessary to create a test harness / application.? It should not be necessary to persist any data to a database...all data should be stored in dataset (it is only a prototype after all!). ## None Functional Requirements ·? ? ? ? ? ? ? ? Written in C# and Asp.net (using .net 3.5) ·? ? ? ? ? ? ? ? Good comments throughout ·? ? ? ? ? ? ? ? No 3rd party products should be used ## Requirements ### Single e-mail send Must be able to specify and select from all the usual e-mail options including ·? ? ? ? ? ? ? ?

Option to request a request a Read Receipt Any errors during sending should be thrown as an exception ### Bulk e-mail send Using the same or similar code for sending a single email, we also need to be able to send bulk e-mails.? The code for this will be performed by a windows service with the results being recorded in a dataset with 6 status’s/options (In-Progress (e.g. not sent yet), Unopened (e.g. sent but the user hasn’t done anything with it), Opened, Clicked Link, Bounced, Unsubscribed) with their IP address (if possible). ·? ? ? ? ? ? ? ? Facility to unsubscribe (A hyperlink at the bottom on the link that sends their e-mail address and the campaign id) ·? ? ? ? ? ? ? ?

Tracking of hyperlinks contained within the sent e-mail ·? ? ? ? ? ? ? ? Tracking of Bounced e-mails (e.g. address doesn’t exist) ### Receive e-mail There should be a windows service to read e-mails from a specified pop3 account(s).? For the purposes of the project it is sufficient to populate incoming data into a dataset.? Once read an e-mail should be left on the server if the option is selected.? An e-mail should only be downloaded once e.g. like Outlook once downloaded it won’t download it again. Attachments should be downloaded to a folder and a hyperlink(s) to the file included in the dataset. ### Other Must be able to specify account details etc. ? ## Class Diagram email ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? account ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? pop3 ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? servername? ??" the name of the pop3 server ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? port ??" the name of the pop3 port ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? username ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? password ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?
