International Email
International email arises from the combined provision of ''internationalized domain names'' (IDN) and '' email address internationalization'' (EAI).Started with: The result is email that contains international characters (characters which do not exist in the ASCII character set), encoded as UTF-8, in the email header and in supporting mail transfer protocols. The most significant aspect of this is the allowance of email addresses (also known as email identities) in most of the world's writing systems, at both interface and transport levels. Email addresses Traditional email addresses are limited to characters from the English alphabet and a few other special characters. The following are valid traditional email addresses: [email protected] (English, ASCII) [email protected] (English, ASCII) user+mailbox/[email protected] (English, ASCII) !#$%&'*+-/=?^_`[email protected] (English, ASCII) ...

Internationalized Domain Name
An internationalized domain name (IDN) is an Internet domain name that contains at least one label displayed in software applications, in whole or in part, in non-Latin script or alphabet or in the Latin alphabet-based characters with diacritics or ligatures. These writing systems are encoded by computers in multibyte Unicode. Internationalized domain names are stored in the Domain Name System (DNS) as ASCII strings using Punycode transcription. The DNS, which performs a lookup service to translate mostly user-friendly names into network addresses for locating Internet resources, is restricted in practice to the use of ASCII characters, a practical limitation that initially set the standard for acceptable domain names. The internationalization of domain names is a technical solution to translate names written in language-native scripts into an ASCII text representation that is compatible with the DNS. Internationalized domain names can only be used with applications that a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arabic Script
The Arabic script is the writing system used for Arabic (Arabic alphabet) and several other languages of Asia and Africa. It is the second-most widely used alphabetic writing system in the world (after the Latin script), the second-most widely used List of writing systems by adoption, writing system in the world by number of countries using it, and the third-most by number of users (after the Latin and Chinese characters, Chinese scripts). The script was first used to write texts in Arabic, most notably the Quran, the holy book of Islam. With Spread of Islam, the religion's spread, it came to be used as the primary script for many language families, leading to the addition of new letters and other symbols. Such languages still using it are Arabic language, Arabic, Persian language, Persian (Western Persian, Farsi and Dari), Urdu, Uyghur language, Uyghur, Kurdish languages, Kurdish, Pashto, Punjabi language, Punjabi (Shahmukhi), Sindhi language, Sindhi, South Azerbaijani, Azerb ...

Digital India
Digital India is a campaign launched by the Government of India to make its services available to citizens electronically via improved online infrastructure and by increasing Internet connectivity. The initiative includes plans to connect rural areas with high-speed internet networks. It consists of three core components: the development of secure and stable digital infrastructure, delivering government services digitally, and universal digital literacy. Indian Prime Minister Narendra Modi launched the program on 1 July 2015. Digital India campaign supports other Government of India schemes, such as BharatNet, Make in India, Standup India, industrial corridors, Bharatmala Sagarmala and Amrit Bharat Station Scheme, Atmanirbhar Bharat.

Email Address Internationalization
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 ''examp ...

Amavis
Amavis is an open-source content filter for electronic mail, implementing mail message transfer, decoding, some processing and checking, and interfacing with external content filters to provide protection against spam and viruses and other malware. It can be considered an interface between a mailer ( MTA, Mail Transfer Agent) and one or more content filters. ''Amavis'' can be used to: * detect viruses, spam, banned content types or syntax errors in mail messages * block, tag, redirect (using sub-addressing), or forward mail depending on its content, origin or size * quarantine (and release), or archive mail messages to files, to mailboxes, or to a relational database * sanitize passed messages using an external sanitizer * generate DKIM signatures * verify DKIM signatures and provide DKIM-based whitelisting Notable features: * provides SNMP statistics and status monitoring using an extensive MIB with more than 300 variables * provides structured event log in JSON format * I ...

Simple Mail Transfer Protocol
The Simple Mail Transfer Protocol (SMTP) is an Internet standard communication protocol for electronic mail transmission. Mail servers and other message transfer agents use SMTP to send and receive mail messages. User-level email clients typically use SMTP only for sending messages to a mail server for relaying, and typically submit outgoing email to the mail server on port 465 or 587 per . For retrieving messages, IMAP (which replaced the older POP3) is standard, but proprietary servers also often implement proprietary protocols, e.g., Exchange ActiveSync. SMTP's origins began in 1980, building on concepts implemented on the ARPANET since 1971. It has been updated, modified and extended multiple times. The protocol version in common use today has extensible structure with various extensions for authentication, encryption, binary data transfer, and internationalized email addresses. SMTP servers commonly use the Transmission Control Protocol on port number 25 (between se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Message Transfer Agent
Within the Internet email system, a message transfer agent (MTA), mail transfer agent, or mail relay is software that transfers electronic mail messages from one computer to another using the Simple Mail Transfer Protocol. In some contexts, the alternative names mail server, mail exchanger, or MX host are used to describe an MTA. Messages exchanged across networks are passed between mail servers, including any attached data files (such as images, multimedia, or documents). These servers often keep mailboxes for email. Access to this email by end users is typically either by webmail or an email client. Operation A message transfer agent receives mail from either another MTA, a mail submission agent (MSA), or a mail user agent (MUA). The transmission details are specified by the Simple Mail Transfer Protocol (SMTP). When a recipient mailbox of a message is not hosted locally, the message is relayed, that is, forwarded to another MTA. Every time an MTA receives an email message, it ...
