Getmail
getmail is a simple mail retrieval agent intended as a replacement for fetchmail, implemented in Python. It can retrieve mail from POP3, IMAP4, and ''Standard Dial-up POP3 Service'' servers, with or without SSL. It supports simple and domain (multidrop) mailboxes, mail filtering via any arbitrary program, and supports a wide variety of mail destination types, including mboxrd, maildir, and external arbitrary mail delivery agents. Unlike fetchmail, getmail's Python foundation makes it nearly immune to buffer overflow security holes. It also has a simpler configuration syntax than fetchmail, but supports fewer authentication protocols. The software can also function as a basic mail delivery agent. Getmail is free software and is licensed under the GNU General Public License version 2. It is written and maintained by Charles Cazabon. The original getmail software requires Python 2, which is no longer supported. A fork named getmail6, which is not from getmail's original author, ...

Fetchmail
Fetchmail is an open-source software utility for POSIX-compliant operating systems which is used to retrieve e-mail from a remote POP3, IMAP, or ODMR mail server to the user's local system. It was developed from thpopclientprogram, written by Carl Harris. Its chief significance is perhaps that its author, Eric S. Raymond, used it as a model to discuss his theories of open-source software development in a widely read and influential essay on software development methodologies ''The Cathedral and the Bazaar''. Design By design, Fetchmail's only means of delivering messages is by submitting them to the local MTA/Message transfer agent or invoking a mail delivery agent like procmail, maildrop, or sendmail; delivering directly to mail folders such as maildir is not supported. Dan Bernstein, getmail creator Charles Cazabon and FreeBSD developer Terry Lambert, have criticized Fetchmail's design, its number of security holes, and that it was prematurely put into "maintenance mode". ...

Mail Delivery Agent
A message delivery agent (MDA), or mail delivery agent, is a computer software component that is responsible for the delivery of e-mail messages to a local recipient's mailbox., ''Internet Mail Architecture'', D. Crocker (July 2009) It is also called a local delivery agent (LDA). Within the Internet mail architecture, local message delivery is achieved through a process of handling messages from the message transfer agent, and storing mail into the recipient's environment (typically a mailbox). Implementation Many mail handling software products bundle multiple message delivery agents with the message transfer agent component, providing for site customization of the specifics of mail delivery to a user. Unix On Unix-like systems, procmail and maildrop are the most popular MDAs. The Local Mail Transfer Protocol (LMTP) is a protocol that is frequently implemented by network-aware MDAs. Invocation The mail delivery agent is generally not started from the command line, bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mail Retrieval Agent
A mail retrieval agent (MRA) is a computer application that retrieves or fetches e-mail from a remote mail server and works with a mail delivery agent to deliver mail to a local or remote email mailbox. MRAs may be external applications by themselves or be built into bigger applications like a mail user agent. Significant examples of standalone MRAs include fetchmail and getmail. The concept of an MRA is not standardized in email architecture. Although they operate like mail transfer agents, MRAs are technically clients when they retrieve and submit messages. Delivery mechanisms The mail retrieval agent may support delivery of retrieved mail via the following mechanisms: * Via a mail transport agent (Listening for SMTP transfers on port 25) * Via a mail delivery agent * Direct delivery to an mbox formatted mailbox * Direct delivery to a maildir directory * Output to standard output Multiple mailbox support The mail retriever agent may support retrieval of mail from multiple m ...

OfflineIMAP
OfflineIMAP is IMAP synchronization utility software, capable of synchronizing mail on IMAP server with local Maildir folder or another server. Description The synchronization is performed bidirectionally between two endpoints ("Remote" and "Local" repositories). OfflineIMAP accesses mail servers only via Internet Message Access Protocol (Post Office Protocol – another popular way to get mail from server – is not supported), it works faster (though it is sensitive to connection's latency) and supports more advanced features than most mail clients. The special mode for better handling the non-standard implementation of IMAP in Gmail may optionally be enabled in a configuration file. When configured to store mail locally, OfflineIMAP uses the Maildir format. Unix mail boxes support may be added in the future, though currently it is not implemented. Configuration Several synchronizations account, each consisting of Remote and Local repositories, may be defined in config ...

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] |
Unix-like
A Unix-like (sometimes referred to as UN*X or *nix) operating system is one that behaves in a manner similar to a Unix system, although not necessarily conforming to or being certified to any version of the Single UNIX Specification. A Unix-like application is one that behaves like the corresponding Unix command or shell. Although there are general philosophies for Unix design, there is no technical standard defining the term, and opinions can differ about the degree to which a particular operating system or application is Unix-like. Some well-known examples of Unix-like operating systems include Linux and BSD. These systems are often used on servers, as well as on personal computers and other devices. Many popular applications, such as the Apache web server and the Bash shell, are also designed to be used on Unix-like systems. One of the key features of Unix-like systems is their ability to support multiple users and processes simultaneously. This allows users to run mult ...

O'Reilly Media
O'Reilly Media (formerly O'Reilly & Associates) is an American learning company established by Tim O'Reilly that publishes books, produces tech conferences, and provides an online learning platform. Its distinctive brand features a woodcut of an animal on many of its book covers. Company Early days The company began in 1978 as a private consulting firm doing technical writing, based in the Cambridge, Massachusetts area. In 1984, it began to retain publishing rights on manuals created for Unix vendors. A few 70-page "Nutshell Handbooks" were well-received, but the focus remained on the consulting business until 1988. After a conference displaying O'Reilly's preliminary Xlib manuals attracted significant attention, the company began increasing production of manuals and books. The original cover art consisted of animal designs developed by Edie Freedman because she thought that Unix program names sounded like "weird animals".

Fdm (software)
fdm (fetch/filter and deliver mail) is a mail delivery agent and email filtering software for Unix-like operating systems, similar to fetchmail and procmail. It was started in 2006 by Nicholas Marriott who later also started tmux in 2007. Adoption fdm is available as a package in many Unix-like operating systems. It has been included in OpenBSD ports since 2007-01-18. When in 2014 the last maintainer of procmail posted a message to an OpenBSD mailing list himself suggesting that he remove the procmail port, it has been suggested by a well-known OpenBSD ports maintainer that fdm is the natural alternative (the procmail port, however, has not been removed and remains in place as of 2020). fdm is listed on the OpenBSD Innovations page, in the section of projects maintained by OpenBSD developers outside of OpenBSD.
