Internet Message Access Protocol
In computing, the Internet Message Access Protocol (IMAP) is an Internet standard protocol used by email clients to retrieve email messages from a mail server over a TCP/IP connection. IMAP is defined by . IMAP was designed with the goal of permitting complete management of an email box by multiple email clients, therefore clients generally leave messages on the server until the user explicitly deletes them. An IMAP server typically listens on port number 143. IMAP over SSL/TLS (IMAPS) is assigned the port number 993. Virtually all modern e-mail clients and servers support IMAP, which along with the earlier POP3 (Post Office Protocol) are the two most prevalent standard protocols for email retrieval. Many webmail service providers such as Gmail and Outlook.com also provide support for both IMAP and POP3. Email protocols The Internet Message Access Protocol is an application layer Internet protocol that allows an e-mail client to access email on a remote mail server. The curre ...

Access Control List
In computer security, an access-control list (ACL) is a list of permissions associated with a system resource (object). An ACL specifies which users or system processes are granted access to objects, as well as what operations are allowed on given objects. Each entry in a typical ACL specifies a subject and an operation. For instance, if a file object has an ACL that contains , this would give Alice permission to read and write the file and give Bob permission only to read it. Implementations Many kinds of operating systems implement ACLs or have a historical implementation; the first implementation of ACLs was in the filesystem of Multics in 1965. Filesystem ACLs A filesystem ACL is a data structure (usually a table) containing entries that specify individual user or group rights to specific system objects such as programs, processes, or files. These entries are known as access-control entries (ACEs) in the Microsoft Windows NT, OpenVMS, and Unix-like operating systems s ...

POP3
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. POP version 3 (POP3) is the version in common use, and along with IMAP 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 download 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 the server after download. By contr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WebDAV
WebDAV (Web Distributed Authoring and Versioning) is a set of extensions to the Hypertext Transfer Protocol (HTTP), which allows user agents to collaboratively author contents ''directly'' in an HTTP web server by providing facilities for concurrency control and namespace operations, thus allowing Web to be viewed as a ''writeable, collaborative medium'' and not just a read-only medium. WebDAV is defined in by a working group of the Internet Engineering Task Force (IETF). The WebDAV protocol provides a framework for users to create, change and move documents on a server. The most important features include the maintenance of properties about an author or modification date, namespace management, collections, and overwrite protection. Maintenance of properties includes such things as the creation, removal, and querying of file information. Namespace management deals with the ability to copy and move web pages within a server's namespace. Collections deal with the creation, remo ...

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. Implementations Server-side The following products implement the ''server''-side portion of the CardDAV protocol: ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 to 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 implementatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ActiveSync
ActiveSync is a mobile data synchronization app developed by Microsoft, originally released in 1996. It synchronizes data with handheld devices and desktop computers. In the Windows Task Manager, the associated process is called wcescomm.exe. Overview ActiveSync allows a mobile device to be synchronized with either a desktop PC or a server running a compatible software product. On desktops, ActiveSync synchronizes emails, calendar, contacts and tasks with Microsoft Outlook, along with Internet bookmarks and files. ActiveSync does not support all features of Outlook. For instance, contacts grouped into subfolders are not transferred. Only the contacts which are not in a subfolder are synchronized. In case of Exchange Server, only emails, calendar, contacts and tasks may be synchronized. ActiveSync also provides for the manual transfer of files to a mobile device, along with limited backup functionality, and the ability to install and uninstall mobile device applications. Supp ...

Citadel/UX
Citadel/UX (typically referred to simply as "Citadel") is a collaboration suite (messaging and groupware) that is descended from the Citadel family of programs which became popular in the 1980s and 1990s as a bulletin board system platform. It is designed to run on open source operating systems such as Linux or BSD. Although it is being used for many bulletin board systems, in 1998 the developers began to expand its functionality to a general purpose groupware platform. In order to modernize the Citadel platform for the Internet, the Citadel/UX developers added functionality such as shared calendars, instant messaging, and built-in implementations of Internet protocols such as SMTP, IMAP, Sieve, POP3, GroupDAV and XMPP. All protocols offer OpenSSL encryption for additional security. Users of Citadel/UX systems also have available to them a web-based user interface which employs Ajax style functionality to allow application-like interaction with the system. Citadel uses the Ber ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lightweight Directory Access Protocol
The Lightweight Directory Access Protocol (LDAP ) is an open, vendor-neutral, industry standard application protocol for accessing and maintaining distributed directory information services over an Internet Protocol (IP) network. Directory services play an important role in developing intranet and Internet applications by allowing the sharing of information about users, systems, networks, services, and applications throughout the network. As examples, directory services may provide any organized set of records, often with a hierarchical structure, such as a corporate email directory. Similarly, a telephone directory is a list of subscribers with an address and a phone number. LDAP is specified in a series of Internet Engineering Task Force (IETF) Standard Track publications called Request for Comments (RFCs), using the description language ASN.1. The latest specification is Version 3, published aRFC 4511ref name="gracion Gracion.com. Retrieved on 2013-07-17. (a road map to the ...

ICalendar
The Internet Calendaring and Scheduling Core Object Specification (iCalendar) is a media type which allows users to store and exchange calendaring and scheduling information such as events, to-dos, journal entries, and free/busy information, and together with its associated standards has been a cornerstone of the standardization and interoperability of digital calendars across different vendors. Files formatted according to the specification usually have an extension of .ics. With supporting software, such as an email reader or calendar application, recipients of an iCalendar data file can respond to the sender easily or counter-propose another meeting date/time. The file format is specified in a proposed Internet standard (RFC 5545) for calendar data exchange. iCalendar is used and supported by many products, including Google Calendar, Apple Calendar (formerly iCal), HCL Domino (formerly IBM Notes and Lotus Notes), Yahoo! Calendar, GNOME Evolution, eM Client, Lightning exte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
VCard
vCard, also known as VCF (Virtual Contact File), is a file format standard for electronic business cards. vCards can be attached to e-mail messages, sent via Multimedia Messaging Service (MMS), on the World Wide Web, instant messaging, NFC or through QR code. They can contain name and address information, phone numbers, e-mail addresses, URLs, logos, photographs, and audio clips. vCard is used as data interchange format in smartphone contacts, personal digital assistants (PDAs), personal information managers (PIMs) and customer relationship management (CRMs). To accomplish these data interchange applications, other "vCard variants" have been used and proposed as "variant standards", each for its specific niche: XML representation, JSON representation, or web pages. An unofficial vCard Plus format makes use of a URL to a customized landing page with all the basic information along with a profile photo, geographic location, and other fields. This can also be saved as a conta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
