Email Processing

We want to add email acceptance to our online helpdesk system. We requrie the following. Server Software Windows IIS. We will direct emails at the mail server. The server will receive the email. Take apart the data of the email, i.e. the header content, attachments etc, it will then store all of this information in a SQL database. The system will look for key words in the email and enter these in specific fields. for example. #from: #by: #12345: The system will have an allowed list of email address to recevie email for, any email recioved for an email address that is not allowed wil be returned to sender with a friendly error message. Also a max number of attachments and size of attachments. You will provide an ASP page that can display the email and allow the attachments to be opened. This page will be requried to display all types of emails, HTML, Rich Text etc. The reference for the page to use to display the email will be a unique id created by you. This is internal so no security is required.
