Dovecot (software)
Dovecot is an open-source IMAP and POP3 server for Unix-like operating systems, written primarily with security in mind. Timo Sirainen originated Dovecot and first released it in July 2002. Dovecot developers primarily aim to produce a lightweight, fast and easy-to-set-up open-source email server. The primary purpose of Dovecot is to act as a mail storage server. The mail is delivered to the server using some mail delivery agent (MDA) and is stored for later access with an email client (mail user agent, or MUA). Dovecot can also act as mail proxy server, forwarding connection to another mail server, or act as a lightweight MUA in order to retrieve and manipulate mail on remote server for e.g. mail migration. According to thOpen Email Survey as of 2020, Dovecot has an installed base of at least 2.9million IMAP servers, and has a global market share of 76.9% of all IMAP servers. The results of the same survey in 2019 gave figures of 2.6million and 76.2%, respectively. Features ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |

Comparison Of Mail Servers
The comparison of mail servers covers mail transfer agents (MTAs), mail delivery agents, and other computer software that provide e-mail services. Unix-based mail servers are built using a number of components because a Unix-style environment is, by default, a toolbox operating system. A stock Unix-like server already has internal mail; more traditional ones also come with a full MTA already part of the standard installation. To allow the server to send external emails, an MTA such as Sendmail, Postfix, or Exim is required. Mail is read either through direct access (shell login) or mailbox protocols like POP and IMAP. Unix-based MTA software largely acts to enhance or replace the respective system's native MTA. Microsoft Windows servers do not natively implement e-mail, thus Windows-based MTAs have to supply all the necessary aspects of e-mail-related functionality.

Mac OS X Server
Mac OS X Server is a series of Discontinued software, discontinued Unix-like server operating systems developed by Apple Inc., based on macOS. It provided server functionality and system administration tools, and tools to manage both macOS-based computers and iOS-based devices, network services such as a message transfer agent, mail transfer agent, Apple Filing Protocol, AFP and Server Message Block, SMB servers, an Lightweight Directory Access Protocol, LDAP server, and a Domain Name System, domain name server, as well as server applications including a Web server, database, and Calendar (Apple), calendar server. Starting with OS X Lion, Apple stopped selling a standalone server operating system, instead releasing an add-on Server app marketed as OS X Server (and later macOS Server), which was sold through the Mac App Store. The Server app lacked many features from Mac OS X Server, and later versions of the app only included functionality related to user and group manageme ...

DIGEST-MD5
Digest access authentication is one of the agreed-upon methods a web server can use to negotiate credentials, such as username or password, with a user's web browser. This can be used to confirm the identity of a user before sending sensitive information, such as online banking transaction history. It applies a hash function to the username and password before sending them over the network. In contrast, basic access authentication uses the easily reversible Base64 encoding instead of hashing, making it non-secure unless used in conjunction with TLS. Technically, digest authentication is an application of cryptographic hashing with usage of nonce values to prevent replay attacks. It uses the HTTP protocol. DIGEST-MD5 as a SASL mechanism specified by is obsolete since July 2011. Overview Digest access authentication was originally specified by (''An Extension to HTTP: Digest Access Authentication''). RFC 2069 specifies roughly a traditional digest authentication scheme with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CRAM-MD5
In cryptography, CRAM-MD5 is a challenge–response authentication mechanism (CRAM) based on the HMAC-MD5 algorithm. As one of the mechanisms supported by the Simple Authentication and Security Layer (SASL), it is often used in email software as part of SMTP Authentication and for the authentication of POP and IMAP users, as well as in applications implementing LDAP, XMPP, BEEP, and other protocols. When such software requires authentication over unencrypted connections, CRAM-MD5 is preferred over mechanisms that transmit passwords "in the clear," such as ''LOGIN'' and ''PLAIN''. However, it can't prevent derivation of a password through a brute-force attack, so it is less effective than alternative mechanisms that avoid passwords or that use connections encrypted with Transport Layer Security (TLS). Protocol The CRAM-MD5 protocol involves a single challenge and response cycle, and is initiated by the server: # Challenge: The server sends a base64-encoded string to the client. ...

Message Submission Agent
A message submission agent (MSA), or mail submission agent, is a computer program or software agent that receives electronic mail messages from a mail user agent (MUA) and cooperates with a mail transfer agent (MTA) for delivery of the mail. It uses ESMTP, a variant of the Simple Mail Transfer Protocol (SMTP), as specified in RFC 6409. Many MTAs perform the function of an MSA as well, but there are also programs that are specially designed as MSAs without full MTA functionality. Historically, in Internet mail, both MTA and MSA functions use port number 25, but the official port for MSAs is 587. The MTA accepts a user's incoming mail, while the MSA accepts a user's outgoing mail. Benefits Separation of the MTA and MSA functions produces several benefits. One benefit is that an MSA, since it is interacting directly with the author's MUA, can correct minor errors in a message format (such as a missing ''Date'', ''Message-ID'', ''To'' fields, or an address with a missing domain ...

Post Office Protocol
In computing, the Post Office Protocol (POP) is an application-layer Internet standard protocol used by e-mail clients to retrieve e-mail from a mail server. Today, POP version 3 (POP3) is the most commonly used version. Together with IMAP, it is one of the most common protocols for email retrieval. Purpose The Post Office Protocol provides access via an Internet Protocol (IP) network for a user client application to a mailbox (''maildrop'') maintained on a mail server. The protocol supports list, retrieve and delete operations for messages. POP3 clients connect, retrieve all messages, store them on the client computer, and finally delete them from the server. This design of POP and its procedures was driven by the need of users having only temporary Internet connections, such as dial-up access, allowing these users to retrieve e-mail when connected, and subsequently to view and manipulate the retrieved messages when offline. POP3 clients also have an option to leave mail ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
