Windows Service (SMTP Relay)

I need a windows service creating which will implement the SMTP protocol, essentially it needs to listen on port 25 for incoming messages, when it recieves a message it needs to store the from, to, subject and body fields of the message in an SQL 2005 database. There is no requirement at this stage to store any attachments. When the message has been stored the service simply needs to relay the message to a real smtp server for delivery to the ultimate recipient(s) Note the diagram SMTP Server ^ | Windows Service ^ | Client PC's (Outlook) The service needs to be written in VB.NET 2.0 Thanks ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
