I have a requirement in my project to create dynamic email address on the fly. For example, similar to flickr has the option of uploading photos (or blogger.com has an option of rececing blog posts in predefined email addresses). The email address can be like "[email protected]", once this email address is created what ever the incoming mails will be processed based on certain scenarios.

My questions are:

1. What are the solutions available for having our own IMAP/POP3 Server in Windows? Exchange is not an option though, any commercial softwares will do.
2. Is there any way we can have one real email box and that will be masked with alphanumeric email addresss to minimize the creation of email addresses.
