## Introduction

There is a requirement to send single and bulk e-mails, and track received e-mails from a POP3 account.

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

·? ? ? ? ? ? ? ? To (with ;’s separating names)

·? ? ? ? ? ? ? ? CC

·? ? ? ? ? ? ? ? BCC

·? ? ? ? ? ? ? ? Subject

·? ? ? ? ? ? ? ? Attachments

·? ? ? ? ? ? ? ? Message (in HTML format ??" with embedded images)

·? ? ? ? ? ? ? ? Option to request a request a Delivery Receipt

·? ? ? ? ? ? ? ? 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)

·? ? ? ? ? ? ? ? Suitable code ? to stop specified SMTP server for being blacklisted

·? ? ? ? ? ? ? ? Tracking of opened e-mails

·? ? ? ? ? ? ? ? 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.
