Mailbox Provider
A mailbox provider, mail service provider or, somewhat improperly, email service provider is a provider of email hosting. It implements email servers to send, receive, accept, and store email for other organizations or end users, on their behalf. The term "mail service provider" was coined in the Internet Mail Architecture document . Types There are various kinds of email providers. There are paid and free ones, possibly sustained by advertising. Some allow anonymous users, whereby a single user can get multiple, apparently unrelated accounts. Some require full identification credentials; for example, a company may provide email accounts to full-time staff only. Often, companies, universities, organizations, groups, and individuals that manage their mail servers themselves adopt naming conventions that make it straightforward to identify who is the owner of a given email address. Besides control of the local names, insourcing may provide for data confidentiality, network ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Email
Electronic mail (usually shortened to email; alternatively hyphenated e-mail) is a method of transmitting and receiving Digital media, digital messages using electronics, electronic devices over a computer network. It was conceived in the late–20th century as the digital version of, or counterpart to, mail (hence ''wikt:e-#Etymology 2, e- + mail''). Email is a ubiquitous and very widely used communication medium; in current use, an email address is often treated as a basic and necessary part of many processes in business, commerce, government, education, entertainment, and other spheres of daily life in most countries. Email operates across computer networks, primarily the Internet access, Internet, and also local area networks. Today's email systems are based on a store-and-forward model. Email Server (computing), servers accept, forward, deliver, and store messages. Neither the users nor their computers are required to be online simultaneously; they need to connect, ty ...

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, ...

Email Mailbox
A mailboxISO/IEC 2382:2015 (also electronic mailbox, email box, email mailbox, e-mailbox) is the destination to which electronic mail messages are delivered. It is the equivalent of a letter box in the postal system. Definitions A mailbox is identified by an email address. However, not all email addresses correspond to a storage facility. The term ''pseudo-mailbox'' is sometimes used to refer to an address that does not correspond to a definitive mail store. Email forwarding may be applied to reach end recipients from such addresses. Electronic mailing lists and email aliases are typical examples. RFC 5321, defines an ''email address'' as a character string that identifies a user to whom mail will be sent or a location into which mail will be deposited. The term ''mailbox'' refers to that depository. In that sense, the terms ''mailbox'' and ''address'' can be used interchangeably. RFC 5322 defines a mailbox as follows: ''A mailbox receives mail. It is a 'conceptual entity' tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Email Hosting Service
An email hosting service is an Internet hosting service that operates email servers. Features Email hosting services usually offer premium email as opposed to advertisement-supported free email or free webmail. Email hosting services thus differ from typical end-user email providers such as webmail sites. They cater mostly to demanding email users and small and medium-sized ( SME) businesses, while larger enterprises usually run their own email hosting services on their own equipment using software such as Microsoft Exchange Server, IceWarp, Zoho or Postfix. Hosting providers can manage a user's own domain name, including any email authentication scheme that the domain owner wishes to enforce to convey the meaning that using a specific ''domain name'' identifies and qualifies email senders. Types There are various types of email hosting services. These vary according to the storage space available, location of the mail boxes and functionality. Various hosting providers o ...

Internet Privacy
Internet privacy involves the right or mandate of personal privacy concerning the storage, re-purposing, provision to third parties, and display of information pertaining to oneself via the Internet. Internet privacy is a subset of data privacy. Privacy concerns have been articulated from the beginnings of large-scale computer sharing and especially relate to mass surveillance. Privacy can entail either personally identifiable information (PII) or non-PII information such as a site visitor's behavior on a website. PII refers to any information that can be used to identify an individual. For example, age and physical address alone could identify who an individual is without explicitly disclosing their name, as these two parameters are unique enough to identify a specific person typically. Other forms of PII may include GPS tracking data used by apps, as the daily commute and routine information can be enough to identify an individual. It has been suggested that the "appeal of o ...

ITU-T
The International Telecommunication Union Telecommunication Standardization Sector (ITU-T) is one of the three Sectors (branches) of the International Telecommunication Union (ITU). It is responsible for coordinating Standardization, standards for telecommunications and Information Communication Technology, such as X.509 for cybersecurity, Y.3172 and Y.3173 for machine learning, and H.264/MPEG-4 AVC for video compression, between its Member States, Private Sector Members, and Academia Members. The World Telecommunication Standardization Assembly (WTSA), the sector's governing conference, convenes every four years. ITU-T has a permanent Secretariat (administrative office), secretariat called the Telecommunication Standardization Bureau (TSB), which is based at the ITU headquarters in Geneva, Switzerland. The current director of the TSB is Seizo Onoe (of Japan), whose 4-year term commenced on 1 January 2023. Seizo Onoe succeeded Chaesub Lee of South Korea, who was director from 1 J ...

IETF
The Internet Engineering Task Force (IETF) is a standards organization for the Internet standard, Internet and is responsible for the technical standards that make up the Internet protocol suite (TCP/IP). It has no formal membership roster or requirements and all its participants are volunteers. Their work is usually funded by employers or other sponsors. The IETF was initially supported by the federal government of the United States but since 1993 has operated under the auspices of the Internet Society, a non-profit organization with local chapters around the world. Organization There is no membership in the IETF. Anyone can participate by signing up to a working group mailing list, or registering for an IETF meeting. The IETF operates in a bottom-up task creation mode, largely driven by working groups. Each working group normally has appointed two co-chairs (occasionally three); a charter that describes its focus; and what it is expected to produce, and when. It is open ...

SRV Record
A Service record (SRV record) is a specification of data in the Domain Name System defining the location, i.e., the hostname and port number, of servers for specified services. It is defined in , and its type code is 33. Some Internet protocols such as the Session Initiation Protocol (SIP) and the Extensible Messaging and Presence Protocol (XMPP) often require SRV support by network elements. Record format A SRV record has the form: * ''service'': the symbolic name of the desired service. * ''proto'': the transport protocol of the desired service; this is usually either TCP or UDP. * ''name'': the domain name for which this record is valid, ending in a dot. * ''ttl'': standard DNS time to live field. * ''IN'': standard DNS class field (this is always ''IN''). * ''SRV'': Type of Record (this is always ''SRV''). * ''priority'': the priority of the target host, lower value means more preferred. * ''weight'': A relative weight for records with the same priority, higher value means ...

MX Record
A mail exchanger record (MX record) specifies the mail server responsible for accepting email messages on behalf of a domain name. It is a resource record in the Domain Name System (DNS). It is possible to configure several MX records, typically pointing to an array of mail servers for load balancing and redundancy. Overview Resource records are the basic information element of the Domain Name System (DNS). An MX record is one of these, and a domain may have one or more of these set up, as below: The characteristic payload information of an MX record is a preference value (above labelled "Priority"), and the domain name of a mailserver ("Host" above). The priority field identifies which mailserver should be preferred - in this case the values are both 10, so mail would be expected to flow evenly to both ''onemail.example.com'' and ''twomail.example.com'' - a common configuration. The host name must map directly to one or more address records (A, or AAAA) in the DNS, and mu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Email Address
An email address identifies an email box to which messages are delivered. While early messaging systems used a variety of formats for addressing, today, email addresses follow a set of specific rules originally standardized by the Internet Engineering Task Force (IETF) in the 1980s, and updated by . The term email address in this article refers to just the ''addr-spec'' in Section 3.4 of . The RFC defines ''address'' more broadly as either a ''mailbox'' or ''group''. A ''mailbox'' value can be either a ''name-addr'', which contains a ''display-name'' and ''addr-spec'', or the more common ''addr-spec'' alone. An email address, such as ''[email protected]'', is made up from a local-part, the symbol @, and a '' domain'', which may be a domain name or an IP address enclosed in brackets. Although the standard requires the local-part to be case-sensitive, it also urges that receiving hosts deliver messages in a case-independent manner, e.g., that the mail system in the domain ''ex ...

Domain Name
In the Internet, a domain name is a string that identifies a realm of administrative autonomy, authority, or control. Domain names are often used to identify services provided through the Internet, such as websites, email services, and more. Domain names are used in various networking contexts and for application-specific naming and addressing purposes. In general, a domain name identifies a network domain or an Internet Protocol (IP) resource, such as a personal computer used to access the Internet, or a server computer. Domain names are formed by the rules and procedures of the Domain Name System (DNS). Any name registered in the DNS is a domain name. Domain names are organized in subordinate levels ('' subdomains'') of the DNS root domain, which is nameless. The first-level set of domain names are the ''top-level domains'' (TLDs), including the ''generic top-level domains'' (gTLDs), such as the prominent domains com, info, net, edu, and org, and the ''country code t ...
