Variable Envelope Return Path
Variable envelope return path (VERP) is a technique used by some electronic mailing list software to enable automatic detection and removal of undeliverable e-mail addresses. It works by using a different return path (also called "envelope sender") for each recipient of a message. Motivation Any long-lived mailing list is eventually going to contain addresses that can't be reached. Addresses that were once valid can become unusable because the person receiving the mail there has switched to a different provider. In another scenario, the address may still exist but be abandoned, with unread mail accumulating until there is not enough room left to accept any more. When a message is sent to a mailing list, the mailing list software re-sends it to all of the addresses on the list. The presence of invalid addresses in the list results in bounce messages being sent to the owner of the list. If the mailing list is small, the owner can read the bounce messages and manually remove the inv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electronic Mailing List
A mailing list is a collection of names and addresses used by an individual or an organization to send material to multiple recipients. The term is often extended to include the people subscribed to such a list, so the group of subscribers is referred to as "the mailing list", or simply "the list." Transmission may be paper-based or electronic. Each has its strength, although a 2022 article claimed that "direct mail still brings in the lion’s share of revenue for most organizations." Types At least two types of mailing lists can be defined: * an ''announcement list'' is closer to the original sense, where a "mailing list" of people was used as a recipient for newsletters, periodicals or advertising. Traditionally this was done through the postal system, but with the rise of email, the electronic mailing list became popular. This type of list is used primarily as a one-way conduit of information and may only be "posted to" by selected people. This may also be referred to by t ...

Mercury Mail Transport System
Mercury Mail Transport System (Mercury MTS) is a standards-compliant mail server developed by David Harris, who also develops the Pegasus Mail client. It was freeware prior to January 2007, but is now donationware for non-commercial and personal use, and shareware for other uses. Versions There are two versions of Mercury with similar functionality. The original version, no longer under development, is a set of NetWare Loadable Modules (NLMs) which runs on all versions of the Novell NetWare network operating system (NOS) from 3.x to 6.x (current ). It worked in conjunction with MS-DOS workstations running Pegasus Mail. Mercury/32 is a Win32 application running on all versions of Microsoft Windows from Windows 98 and Windows NT4 to the latest () Windows Vista and Windows Server 2008 (Windows XP or Windows Server 2003 are recommended).

Sympa
''Sympa'' is a Mailing list management (MLM) software. Its name, which is an acronym for ''Système de Multi-Postage Automatique'' (i.e. ''Automatic Mailing System''), also means "nice" ( friendly) in French. Sympa is free and open-source software subject to the terms of the GNU General Public License (GPL).

Its web front-end offers a portal-like interface where the user can control all their list subscriptions and administrative powers in one place (i.e. one site per user, while Mailman (prior to 3.0), for example, creates one site per list). Data is stored in a relational database such as MySQL, PostgreSQL, or Oracle; some configuration data is still held in text files, but the stated goal of the developers is to eventually hold as much configuration data as possible in the database as well. Sympa c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sendmail
Sendmail is a general purpose internetwork email routing facility that supports many kinds of mail-transfer and delivery methods, including the Simple Mail Transfer Protocol (SMTP) used for email transport over the Internet. A descendant of the ''delivermail'' program written by Eric Allman, Sendmail is a well-known project of the free and open source software and Unix communities. It has spread both as free software and proprietary software. Overview Allman had written the original ARPANET delivermail which shipped in 1979 with 4.0 and 4.1 BSD. He wrote Sendmail as a derivative of delivermail in the early 1980s at UC Berkeley. It shipped with BSD 4.1c in 1983, the first BSD version that included TCP/IP protocols. In 1996, approximately 80% of the publicly reachable mail-servers on the Internet ran Sendmail. More recent surveys have suggested a decline, with 3.64% of mail servers in March 2021 detected as running Sendmail in a study performed by E-Soft, Inc. A previous survey ( ...
