C++ API and command line to send and receive emails

We need a library (and a test program) to receive emails from pop3/imap account and to send emails to an smtp server. There are four additional functionalities we need in addition to a normal/expected messaging api: 1. If the email format macthes a pattern (will be specified), the email must be posted to our server using a supplied protocol (The client library (.h and .lib) for will be supplied) 2. Similarly if the account information matches a predefined pattern, the emails of the users at our server must be returned. (The client library (.h and .lib) for will be supplied) 3. The messageIds in the pop3/imap server must be cached locally in a format that will be supplied 4. The messages in pop3/imap server must be moved to a storage server automatically (details will be provided) A command line interface need to be provided as well. In addition, for testing with outlook express, you need to provide: 1. a simple pop3 server 2. a simple smtp server These do not need to be production quality servers as they will be used only for testing. A PHP version, with which this needs to be compatible will be supplied. This should simplify the development efforts considerably, ## 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.
