Cyrus is an IMAP server designed to handle massive quantities of mail, with a number of features not found in other IMAP implementations, including support for: - running the daemon without root privileges; - POP3 and NNTP in addition to plain IMAP; - CalDAV and CardDAV; - secure IMAP using SSL; - server-side filtering with Sieve; - mail users without login accounts; - simple mail quotas; - virtual domains; - IPv6. Cyrus doesn't support reading from and storing mail in the standard mail spool. It stores mail in a separate directory in its own MH-like format. This package contains the common files needed by the other Cyrus components. The cyrus-imapd and/or cyrus-pop3d packages are needed to enable IMAP and POP3 support respectively. cyrus-murder can be used to enable IMAP, POP3 and LMTP proxying. cyrus-replication can be used to provide server replication between two imap servers.
