Lo spool di posta utilizza un layout del file system e un formato simile a maildir utilizzato da altri server come qmail, Courier e Dovecot.
Gli utenti possono accedere alla posta tramite i protocolli IMAP/IMAPS, POP3/POP3S. Il server IMAP Cyrus supporta il filtraggio della posta lato server attraverso l'implementazione di un linguaggio di filtraggio della posta chiamato Sieve.
A partire dalla versione 2.4.17, è stato implementato il supporto per CalDAV e CardDAV per fornire una soluzione integrata di calendario e e-mail, nonché il supporto per la visualizzazione di e-mail tramite un lettore RSS.
History
Prior to 1994, Carnegie Mellon University's email was based on the locally-developed and non-standard Andrew Messaging System (AMS) - written in the early 1980s as part of the Andrew Project. This was very advanced for its day, but had major scalability issues and Carnegie Mellon wanted to move to a standards-compliant mail system that met or exceeded the feature set of AMS.
In 1994 the Computing Services Division at Carnegie Mellon addressed these goals by starting the Cyrus Project. In 1998, Carnegie Mellon placed all of its incoming freshmen (the class of 2002) on the Cyrus server for the first time and in December 2001, bboard access (which had been mirrored from AMS to Cyrus), was cut over to Cyrus completely. AMS was finally phased out in May 2002.
The Computing Services Division later developed Cyrus "Murder" clustering,[N 1] and after several revisions deployed it within Carnegie Mellon in the summer of 2002.
Several members of the Cyrus development team at Carnegie Mellon went on to become leaders in the development of large-scale electronic mail infrastructure elsewhere: John Gardiner Myers was Chief Architect of Host Mail Infrastructure at America Online;[2] and Rob Siemborski worked on Gmail infrastructure at Google.[3]
In the fall of 2016 Carnegie Mellon announced the retirement of Cyrus IMAP as their electronic mail storage service, with Cyrus users required to choose between on-campus Microsoft Exchange and Google "G Suite" off-campus mail.[4]
Cyrus is still being actively developed. Carnegie Mellon University remains active in development, and also provides the infrastructure on which cyrusimap.org runs.[5] Staff at FastMail contribute much of the recent work, as they depend upon it as part of their commercial service.[6][5][7]
