Cyrus IMAP Server
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 JMAP, 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, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carnegie Mellon University
Carnegie Mellon University (CMU) is a private research university in Pittsburgh, Pennsylvania, United States. The institution was established in 1900 by Andrew Carnegie as the Carnegie Technical Schools. In 1912, it became the Carnegie Institute of Technology and began granting four-year degrees.

Kerberized Post Office Protocol
In computing, the Post Office Protocol (POP) is an application-layer Internet standard protocol used by e-mail clients to retrieve e-mail from a mail server. Today, POP version 3 (POP3) is the most commonly used version. Together with IMAP, it is one of the most common protocols for email retrieval. Purpose The Post Office Protocol provides access via an Internet Protocol (IP) network for a user client application to a mailbox (''maildrop'') maintained on a mail server. The protocol supports list, retrieve and delete operations for messages. POP3 clients connect, retrieve all messages, store them on the client computer, and finally delete them from the server. This design of POP and its procedures was driven by the need of users having only temporary Internet connections, such as dial-up access, allowing these users to retrieve e-mail when connected, and subsequently to view and manipulate the retrieved messages when offline. POP3 clients also have an option to leave mail on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gmail
Gmail is the email service provided by Google. it had 1.5 billion active user (computing), users worldwide, making it the largest email service in the world. It also provides a webmail interface, accessible through a web browser, and is also accessible through the official mobile application. Google also supports the use of third-party email clients via the Post Office Protocol, POP and Internet Message Access Protocol, IMAP protocols. At its launch in 2004, Gmail (or Google Mail at the time) provided a storage capacity of one gigabyte per user, which was significantly higher than its competitors offered at the time. Today, the service comes with 15 gigabytes of storage for free for individual users, which is divided among other Google services, such as Google Drive, and Google Photos. Users in need of more storage can purchase Google One to increase this 15 GB limit across most Google services. Users can receive emails up to 50 megabytes in size, including attachments, ...

Collective Noun
In linguistics, a collective noun is a word referring to a collection of things taken as a whole. Most collective nouns in everyday speech are not specific to one kind of thing. For example, the collective noun "group" can be applied to people ("a group of people"), or dogs ("a group of dogs"), or objects ("a group of stones"). Some collective nouns are specific to one kind of thing, especially terms of venery, which identify groups of specific animals. For example, "pride" as a term of venery always refers to lions, never to dogs or cows. Other examples come from popular culture such as a group of owls, which is called a "parliament". Different forms of English handle verb agreement with collective count nouns differently. For example, users of British English generally accept that collective nouns take either singular or plural verb forms depending on context and the metonymic shift that it implies, while in some other forms of English the verb agreement is less flexible. ...

Bulletin Board System
A bulletin board system (BBS), also called a computer bulletin board service (CBBS), is a computer server running list of BBS software, software that allows users to connect to the system using a terminal program. Once logged in, the user performs functions such as uploading and downloading software and data, reading news and bulletins, and exchanging messages with other users through public Internet forum, message boards and sometimes via direct synchronous conferencing, chatting. In the early 1980s, message networks such as FidoNet were developed to provide services such as M+NetMail, NetMail, which is similar to internet-based email. Many BBSes also offered BBS door, online games in which users could compete with each other. BBSes with multiple phone lines often provided chat rooms, allowing users to interact with each other. Bulletin board systems were in many ways a precursor to the modern form of the World Wide Web, social networking service, social networks, and other aspe ...

Freshman
A freshman, fresher, first year, or colloquially frosh, is a person in the first year at an educational institution, usually a secondary school or at the college and university level, but also in other forms of post-secondary educational institutions. Albania In Albania the freshman/woman is called "fruth", which literally means "measles". The etymology of it is "a person that has not yet passed the social measles", social measles referring to the transformation of social skills that usually takes place in the first year of university. Freshmen/women are regarded as socially inept. Arab world In much of the Arab world, a first-year is called a (; plural , ), which is Arabic for "beginner". Brazil In Brazil, students that pass the vestibulares and begin studying in a college or university are called "calouros" or more informally "bixos" ("bixetes" for girls), an alternate spelling of "bicho", which means "animal" (although commonly used to refer to bugs). Calouros are of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Simple Authentication And Security Layer
Simple Authentication and Security Layer (SASL) is a framework for authentication and data security in Internet protocols. It decouples authentication mechanisms from application protocols, in theory allowing any authentication mechanism supported by SASL to be used in any application protocol that uses SASL. Authentication mechanisms can also support ''proxy authorization'', a facility allowing one user to assume the identity of another. They can also provide a ''data security layer'' offering ''data integrity'' and ''data confidentiality'' services. DIGEST-MD5 provides an example of mechanisms which can provide a data-security layer. Application protocols that support SASL typically also support Transport Layer Security (TLS) to complement the services offered by SASL. John Gardiner Myers wrote the original SASL specification (RFC 2222) in 1997. In 2006, that document was replaced by RFC 4422 authored by Alexey Melnikov and Kurt D. Zeilenga. SASL, as defined by RFC 4422 is an I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
News Aggregator
In computing, a news aggregator, also termed a feed aggregator, content aggregator, feed reader, news reader, or simply an aggregator, is client software or a web application that aggregates digital Content (media), content such as online newspapers, blogs, podcasts, and Video logging, video blogs (vlogs) in one location for easy viewing. The updates distributed may include journal tables of contents, podcasts, videos, and news items. Contemporary news aggregators include MSN, Yahoo! News, Feedly, Inoreader, and Mozilla Thunderbird. Function Aggregation technology often consolidates (sometimes Web syndication, syndicated) web content into one page that can show only the new or updated information from many sites. Aggregators reduce the time and effort needed to regularly check websites for updates, creating a unique information space or ''personal newspaper''. Once subscribed to a feed, an aggregator is able to check for new content at user-determined intervals and retrieve t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CardDAV
vCard Extensions to WebDAV (CardDAV) is an address book client/server protocol designed to allow users to access and share contact data on a server. The CardDAV protocol was developed by the IETF and was published as in August 2011. CardDAV is based on WebDAV, which is based on HTTP, and it uses vCard for contact data. History CardDAV was proposed as an open standard for contact management in August 2011. It became known as a synchronization protocol in iOS 7, among other things, and is now also supported by Gmail, where it replaces the no longer supported (by Google) ActiveSync standard. In October 2013, the standard received an update that made it possible to capture higher-resolution contact images and achieve lower data consumption. Specification The specification has been proposed as a standard by IETF as thRFC 6352in August 2011 by C. Daboo from Apple Inc.

CalDAV
Calendaring Extensions to WebDAV, or CalDAV, is an Internet standard allowing a client to access and manage calendar data along with the ability to schedule meetings with users on the same or on remote servers. It lets multiple users in different locations share, search and synchronize calendar data. It extends the WebDAV (HTTP-based protocol for data manipulation) specification and uses the iCalendar format for the calendar data. The access protocol is defined by . Extensions to CalDAV for scheduling are standardized as . The protocol is used by many important open-source applications. History The ''CalDAV'' specification was first published in 2003 as an Internet Draft submitted to the Internet Engineering Task Force (IETF) by Lisa Dusseault. In March 2007, the ''CalDAV'' specification was finished and published by the IETF as RFC 4791, authored by Cyrus Daboo (Apple), Bernard Desruissaux (Oracle), and Lisa Dusseault (CommerceNet). ''CalDAV'' is designed for implementation b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
