Email Service 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 (email or e-mail) is a method of exchanging messages ("mail") between people using electronic devices. Email was thus conceived as the electronic ( digital) version of, or counterpart to, mail, at a time when "mail" meant only physical mail (hence '' e- + mail''). Email later became a ubiquitous (very widely used) communication medium, to the point that 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'' is the medium, and each message sent therewith is also called an ''email.'' The term is a mass noun. Email operates across computer networks, primarily the Internet, and also local area networks. Today's email systems are based on a store-and-forward model. Email servers accept, forward, deliver, and store messages. Neither the users nor their computers are required to be online simult ...

Yahoo! Mail
Yahoo! Mail is an email service launched on October 8, 1997, by the American company Yahoo (2017–present), Yahoo, Inc. The service is free for personal use, with an optional monthly fee for additional features. Business email was previously available with the Yahoo! Small Business brand, before it transitioned to Verizon Communications, Verizon Small Business Essentials in early 2022. As of January 2020, Yahoo! Mail has 225 million users. Users are able to access and manage their mailboxes using webmail, webmail interface, accessible using a standard web browser. Some accounts also supported the use of standard mail protocols (Post Office Protocol, POP3 and Simple Mail Transfer Protocol, SMTP). Since 2015, users can also connect non-Yahoo e-mail accounts to the webmail client. New Yahoo! Mail accounts, and most of the service's accounts, use yahoo.com as the email suffix. Previously, users could choose ymail.com or RocketMail, rocketmail.com as a suffix, or one of several coun ... [...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 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. Since the beginning of the Internet today, email has been the major mode of communication with more benefits and features. Premium email, as opposed to ad-supported free email or free webmail, is ...

Internet Service Provider
An Internet service provider (ISP) is an organization that provides services for accessing, using, or participating in the Internet. ISPs can be organized in various forms, such as commercial, community-owned, non-profit, or otherwise privately owned. Internet services typically provided by ISPs can include Internet access, Internet transit, domain name registration, web hosting, Usenet service, and colocation. An ISP typically serves as the access point or the gateway that provides a user access to everything available on the Internet. Such a network can also be called as an eyeball network. History The Internet (originally ARPAnet) was developed as a network between government research laboratories and participating departments of universities. Other companies and organizations joined by direct connection to the backbone, or by arrangements through other connected companies, sometimes using dialup tools such as UUCP. By the late 1980s, a process was set in place towa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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' that d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Internet Privacy
Internet privacy involves the right or mandate of personal privacy concerning the storing, re-purposing, provision to third parties, and displaying of information pertaining to oneself via Internet. Internet privacy is a subset of data privacy. Privacy concerns have been articulated from the beginnings of large-scale computer sharing. 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 factors are unique enough to identify a specific person typically. Other forms of PII may soon 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 online services is to broadcast personal infor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ITU-T
The ITU Telecommunication Standardization Sector (ITU-T) is one of the three sectors (divisions or units) of the International Telecommunication Union (ITU). It is responsible for coordinating 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 first meeting of the World Telecommunication Standardization Assembly (WTSA), the sector's governing conference, took place on 1 March of that year. ITU-T has a permanent secretariat called the Telecommunication Standardization Bureau (TSB), which is based at the ITU headquarters in Geneva, Switzerland. The current director of the TSB is Chaesub Lee (of South Korea), whose first 4-year term commenced on 1 January 2015, and whose second 4-year term commenced on 1 January 2019. Chaesub Lee succeeded Malcolm Johnson (Director), Malc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IETF
The Internet Engineering Task Force (IETF) is a standards organization for the 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, an international non-profit organization. Organization The IETF is organized into a large number of working groups and birds of a feather informal discussion groups, each dealing with a specific topic. The IETF operates in a bottom-up task creation mode, largely driven by these working groups. Each working group has an appointed chairperson (or sometimes several co-chairs); a charter that describes its focus; and what it is expected to produce, and when. It is open to all who want to particip ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 iRFC 2782 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._proto.name. ttl IN SRV priority weight port target. * ''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 re ...

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: Domain TTL Class Type Priority Host example.com. 1936 IN MX 10 onemail.example.com. example.com. 1936 IN MX 10 twomail.example.com. 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.ex ...

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 RFC 5322. 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 ''john.smith@example.com'', 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 ...
