The user-configurable email address system allows users to select an desired email address at which they receive their email. For example, a student named John Smith with UNI js1999 might choose the email address "john.smith@columbia.edu", and would then be able to share that email address with friends and colleagues.
There is no ID System specification for this project. Some parts of the project that fit into the Unified Forwarding project have been designed and implemented.
