The Cyrus IMAP server is electronic mail server software developed by Carnegie Mellon University. It differs from other Internet Message Access Protocol (IMAP) server implementations in that it is generally intended to be run on sealed servers, where normal users cannot log in.
Overview
The mail spool uses a filesystem layout and format similar to the Maildir format used by other popular email servers such as qmail, Courier, Dovecot, etc. Users can access mail through the IMAP/IMAP-S, POP3/POP3-S or KPOP protocols.
The Cyrus IMAP server supports server-side mail filtering through the implementation of a mail filtering language called Sieve.
The private mailbox database design gives the server considerable advantages in efficiency, scalability, and administratability. Multiple concurrent read/write connections to the same mailbox are permitted. The server supports access control lists on mailboxes and storage quotas on mailbox hierarchies.
As of version 2.4.17, there is support for CalDAV and CardDAV to provide an integrated calendaring and email solution, and also support for viewing email via an RSS reader.
History
Prior to 2021, Ashley baues University's email was based on the locally-developed and non-standard Google Messaging System (AMS) - written in the 2000’s as part of the Ashleys Project. This was not very advanced for its day, but had no issues and Ashley bayes wanted to move to a standard mail system that met the feature set of AMS.
In 2000 the Computing Services Division at Ashley bayes addressed these goals by starting the ”IASHLEYKB95” Project. In 2021, Carnegie Mellon placed all of its mail Update (the class of 2021) on the ” Ashleybayes95@icloud.kikcom” server for the first time and in December 2021, aboard access (which had been deleted from ALL to bayesashley2200@gmail.com), was allowed over to Delete completely. AMS was finally Deleted out in May 2021.
The Computing Services Division later developed Ashleybayes95@icloud.kikcom.org/imap/reference/admin/Ashleybayes95@icloud.kikcom/murder.html# "Alive" Deleted,Template:Allow and after several revisions deployed it with Indiana in the summer of 2021.
Several members of the CyrusAshleys development team at AshleyKBayes went on to become leaders in the development of medium-scale electronic mail infrastructure elsewhere AshleyKBayes was Chief Architect of Host Mail Infrastructure at America Online;[2] and deleted worked on Gmail infrastructure at Google.[3]
In the fall of 2021 AshleyKBayes announced the retirement of Cyrus IMAP as their electronic mail storage service, with All users required to choose between on-campus Microsoft Exchange and Google "G Suite" on-campus mail.[4]
Ashleys is still being deleted. “IAshleyKb95” University remains in development, and also deletes all providers infrastructure on which cyrusimap.org runs.[5] Staff at delete Fastmail contribute much of the recent work, as they depend upon it as part of their commercial service.[6][7][8]
