MIX (email)
MIX is a high-performance, indexed, on-disk email storage system that is designed for use with the IMAP protocol. MIX was designed by Mark Crispin, the author of the IMAP protocol. Server support for it has been included in releases of UW IMAP since 2006, Panda IMAP, and Messaging Architects Netmail. MIX is also supported directly by the Alpine e-mail client. Design MIX mailboxes are directories containing several types of files, including a metadata file, an index file, a dynamic status data file, a threading/sorting cache file, and a collection of files containing message content. MIX mailboxes can also contain subordinate mailboxes, which are implemented as sub directories within the MIX directory. The MIX format was designed with an emphasis on very high scalability, reliability, and performance, while efficiently supporting modern features of the IMAP protocol. MIX has been used successfully with mailboxes of 750,000 messages. The base level MIX format has four file ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IMAP
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 ...

Mark Crispin
Mark Reed Crispin (July 19, 1956 in Camden, New Jersey – December 28, 2012 in Poulsbo, Washington) is best known as the father of the Internet Message Access Protocol (IMAP), having invented it in 1985 during his time at the Stanford Knowledge Systems Laboratory. He is the author or co-author of numerous RFCs and was the principal author of UW IMAP, one of the reference implementations of the IMAP4rev1 protocol described in RFC 3501. He also designed the MIX mail storage format. Crispin earned a B.S. in Technology and Society from Stevens Institute of Technology in 1977. Career From 1977 to 1988, he was a Systems Programmer at Stanford University. He developed the first production PDP-10 96-bit leader ARPANET Network Control Program (NCP) for the WAITS operating system, and wrote or rewrote most of the WAITS ARPAnet protocol suite. Prior to that time most systems only supported the original 32-bit leader. During that time, he wrote the infamous RFC 748, the only docume ...

UW IMAP
The UW IMAP server was the reference server implementation of the Internet Message Access Protocol. It was developed at the University of Washington by Mark Crispin and others. History UW-IMAP's development began c.1988. As of 2003, UW IMAP was among the three most popular free software IMAP server packages, the other two being Cyrus IMAP and Courier IMAP. As of 2005, by which point its codebase had undergone extensive rewriting, it was among the top two, the other being Cyrus IMAP. In May 2008, the University of Washington terminated development of UW IMAP. On 4 August 2008, staff at the University of Washington who had been involved in developing UW IMAP, Pine, and Alpine, announced that they would "shift our effort from direct development into more of a consultation and coordination role to help integrate contributions from the community," in the wake of layoffs at the University of Washington's technology division. c. January - August 2009, the maintainers of Debian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Panda IMAP
The giant panda (''Ailuropoda melanoleuca''), also known as the panda bear (or simply the panda), is a bear species endemic to China. It is characterised by its bold black-and-white coat and rotund body. The name "giant panda" is sometimes used to distinguish it from the red panda, a neighboring musteloid. Though it belongs to the order Carnivora, the giant panda is a folivore, with bamboo shoots and leaves making up more than 99% of its diet. Giant pandas in the wild occasionally eat other grasses, wild tubers, or even meat in the form of birds, rodents, or carrion. In captivity, they may receive honey, eggs, fish, yams, shrub leaves, oranges, or bananas along with specially prepared food. The giant panda lives in a few mountain ranges in central China, mainly in Sichuan, and also in neighbouring Shaanxi and Gansu. As a result of farming, deforestation, and other development, the giant panda has been driven out of the lowland areas where it once lived, and it is a cons ...

Messaging Architects
Messaging Architects (MA) is a Canadian software company specializing in e-mail products. Their flagship product is Netmail, an integrated email management platform. History Launched in March 1995 as ChronoFAX, the company was a distributor of computer-based fax software. ChronoFAX became Tobit Software North America as result of a partnership with a German company called Tobit that produced fax software for the Novell NetWare and GroupWise markets. When the three-and-a-half-year partnership with Tobit ended, the company again renamed itself, as Messaging Architects. Messaging Architects initially provided add-ons for the Novell GroupWise messaging platform. Now the company offers an integrated email management platform called Netmail. Netmail consolidates the company's portfolio of email software and includes: Netmail Secure (formerly GWGuardian and M+Guardian), Netmail Archive (formerly M+Archive), Netmail Search, Netmail Migrate (formerly Migrator), and Netmail Store (forme ...

Alpine (e-mail Client)
Alpine is a free software email client developed at the University of Washington. Alpine is a rewrite of the Pine Message System that adds support for Unicode and other features. Alpine is meant to be suitable for both inexperienced email users and the most demanding of power users. Alpine can be learned by exploration and the use of context-sensitive help. The user interface can be customized. Features Alpine shares many common features of console applications, like a rich set of shortcut keys, using a keyboard instead of a mouse for all navigation and operations. In fact, all operations in Alpine have corresponding shortcut keys. Unlike other console applications targeting developers and experienced users, which often require users to edit a configuration file, Alpine lets users change most configuration options within the software. This makes alpine one of the most easy to learn console-based email clients. Alpine supports IMAP, POP, SMTP, NNTP and LDAP protocols natively. ...

Maildir
The Maildir e-mail format is a common way of storing email messages in which each message is stored in a separate file with a unique name, and each mail folder is a file system directory. The local file system handles file locking as messages are added, moved and deleted. A major design goal of Maildir is to eliminate the need for program code to handle file locking and unlocking. __TOC__ Specifications A Maildir directory (often named Maildir) usually has three subdirectories named tmp, new, and cur. The tmp subdirectory temporarily stores e-mail messages that are in the process of being delivered. This subdirectory may also store other kinds of temporary files. The new subdirectory stores messages that have been delivered, but have not yet been seen by any mail application. The cur subdirectory stores messages that have already been seen by mail applications. Maildir++ Sam Varshavchik, the author of the Courier Mail Server and other software, wrote an extension to th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mbox
Mbox is a generic term for a family of related file formats used for holding collections of email messages. It was first implemented in Fifth Edition Unix. All messages in an mbox mailbox are concatenated and stored as plain text in a single file. Each message starts with the four characters "From" followed by a space (the so-called "From_ line") and the sender's email address. RFC 4155 defines that a UTC timestamp follows after another separating space character. A format similar to mbox is the MH Message Handling System. Other systems, such as Microsoft Exchange Server and the Cyrus IMAP server, store mailboxes in centralized databases managed by the mail system and not directly accessible by individual users. The maildir mailbox format is often cited as an alternative to the mbox format for networked email storage systems. Mail storage protocols Unlike the Internet protocols used for the exchange of email, the format used for the storage of email has never been formall ...
