Cyrus IMAP server designed for closed systems with restricted user access.
The Cyrus IMAP server is a highly scalable enterprise mail system that is intended to be used in sealed systems where regular users cannot log in. Electronic mail is a crucial infrastructure service in almost all organizations, and the use of electronic mail has been extensive in Carnegie Mellon since the early 1990s, overshadowing all other distributed services. This crucial service is a core part of the business process of most departments. Additionally, the Andrew Mail and Bulletin Board System (AMS) has helped make electronic mail universally available, and departments without AMS have had to run their own mail systems, seeing heavy use as well.
With the end of the lifetime of AMS in sight, the Cyrus Electronic Mail Project has been working on building a new campus mail system that is highly scalable and designed for use in small to large enterprise environments using standardized technologies. The Cyrus technologies can be scaled from independent use in small departments to a system centrally managed in a large enterprise. Visitors to the site can also check out the Cyrus Wiki, which is updated more frequently.
The Cyrus IMAP server provides access to personal mail and system-wide bulletin boards through the IMAP protocol. The full Cyrus IMAP implementation allows for a seamless mail and bulletin board environment to be set up across multiple servers. Unlike other IMAP server implementations, the Cyrus IMAP server is run on sealed servers where users are not normally allowed to log in. The mailbox database is stored in parts of the filesystem that are private to the Cyrus IMAP system, and all user access to mail is through software using the IMAP, POP3, or KPOP protocols.
The private mailbox database design gives the server large advantages in efficiency, scalability, and administrability. Multiple concurrent read/write connections to the same mailbox are permitted, and the server supports access control lists on mailboxes and storage quotas on mailbox hierarchies. Overall, the Cyrus IMAP server offers a highly scalable and secure mail system designed for use in enterprise environments while using standardized technologies.
