Electronic Mail (Cyrus IMAP)
Cyrus IMAP is a part of Project Cyrus, a project developed at Carnegie Mellon University to provide a reliable, scalable electronic mail system for the campus. The Cyrus mail server had, in its original design goals from 1994, many of the same goals of administrators today: the mail service had to scale to thousands of simultaneous readers, it had to support many different clients on different hardware and operating-system platforms, and it had to integrate with the campus-wide authentication system, which happens to be based on Kerberos. Today, Cyrus supports the two major mail access protocols: the Internet Mail Access Protocol (IMAP) and Post Office Protocol (POP). A separate program, a Mail Transfer Agent, handles the task of transferring mail from system to system through the Simple Mail Transfer Protocol (SMTP). Newer mail clients support SMTP authentication, and we’ll discuss Kerberos support for MTAs in the next section.
Cyrus IMAP is available from Carnegie Mellon at http://asg.web.cmu.edu/cyrus/imapd, and the latest stable version available at the time of this writing is 2.1.12. Cyrus IMAP uses the Cyrus SASL library to handle authentication and session encryption tasks. Therefore, before building Cyrus IMAP, you’ll need a working installation of Cyrus SASL.
