A door is a computer program , on a bulletin board system , that runs outside of the main bulletin board program. Sometimes called external programs, doors are the most common way to add games, utilities, and other extensions to BBSes. From the 1990s on, most BBS software had the capability to drop to doors. Several standards were developed for passing connection and user information to doors this was usually done with dropfile s. Most doors were responsible for operating the serial port or other communications device directly until returning control to the BBS. Later development of FOSSIL drivers have allowed both BBSes and their doors to communicate without being responsible for direct operation of the communications hardware. Uses A major use of doors is for door games computer game s played on the BBS. While many of the most popular and memorable BBS doors have been games, numerous doors had non entertainment applications such as user polls or the time bank , permitting users to time shift their rationed BBS use. Frequently they act as a front end to themed databases on subject such as astrology, numerology and fortune telling, recipes, weather prediction, personal ads sometimes with additional match making functionality , classified ads and for sale listings sometimes permitting auctions , BBS lists, and parting comments from the most recent BBS callers. A front door operates in the opposite manner from most doors instead of being launched by the BBS, the front door handles call answering and allows non BBS calls to be dealt with. This allowed BBSes to accept messages and files, on networks such as FidoNet , without the calling system having to know the operating details of the recipient s BBS. Another type of door compiles and transfers BBS messages for the use of offline reader s. Many doors, including Markmail and Qmail, provided QWK file format QWK functionality for convenient use with offline readers. Prodoor provided a different message editor for use wit ... more details

It is best known for its IMAP server component. Courier can function as an intermediate mail relay, between an internal LAN and the Internet, or perform final delivery to mailboxes. Courier uses maildir s as its native storage format and can also deliver mail to legacy mailbox files. Configuration files are in plain text format and may include Perl scripts. Courier can provide mail services for regular operating system accounts. Courier can also provide mail services for virtual mail accounts, managed by any of Lightweight Directory Access Protocol LDAP directory service, Berkeley DB , MySQL or PostgreSQL authentication database. Parts of Courier, such as the maildrop filtering system, the webmail and IMAP server, can also be installed as independent packages which can be used with other mail servers. Courier IMAP is a particularly popular combination with Qmail , Exim , and Postfix software Postfix servers that are configured to use maildirs. Courier s source compiles on most POSIX based operating systems based on Linux and BSD derived kernels. It uses SMTP extensions for list management and spam filtering. A review of SourceForge on February 24, 2009 indicates that Courier had been downloaded from that site over 1,000,000 times ranking 282nd on all packages with numerous http sourceforge.net search ?type of search soft&words courier third party applications See also Comparison of mail servers External links http www. ... more details

The mail spool uses a filesystem layout and format similar to the Maildir format used by other popular email servers such as qmail , Courier Mail Server Courier , Dovecot software Dovecot , etc. Cyrus IMAP s spool format, said By whom date October 2009 to have improved performance and scalability to Maildir, resides in parts of the filesystem that are private to the Cyrus IMAP system. Users can access mail through the IMAP IMAP S, POP3 POP3 S or Kerberized Post Office Protocol KPOP protocols. The Cyrus IMAP server supports server side mail filtering through the implementation of a mail filtering language called Sieve mail filtering language Sieve . The private mailbox database design gives the server considerable advantages in Algorithmic efficiency efficiency , scalability , and administratability . Multiple concurrent read write connections to the same mailbox are permitted. The server supports access control lists on mailboxes and storage quotas on mailbox hierarchies. History Prior to 1994, Carnegie Mellon University exclusively used the locally developed and non standard Andrew Messaging System AMS for its email communication needs. Originally written in the early 1980s as part of the Andrew Project , it was very advanced for its day. However, it had major scalability issues.

How does it work? DBMail is made up of several components. A normal MTA Postfix software Postfix , Sendmail , Qmail , Exim is used for accepting messages. The MTA hands the messages over DBMail for message delivery using either a pipe interface, or LMTP Local Mail Transport Protocol . DBMail then takes care of delivering the message into the database. Messages can be retrieved from the database by any common Mail User Agent using the POP3 protocol or IMAP4 protocol. Features Database driven The whole email is stored in the database, including attachments. The DBMail programs do not have to touch the filesystem to retrieve or insert emails. User information is also stored in the database or in Lightweight Directory Access Protocol LDAP , so users do not need an account on the machines DBMail is running on. DBMail currently supports MySQL Postgresql SQLite LDAP integration DBMail features full LDAP integration for both user authentication login password validation and for user configuration mail addresses and mail forwarding . Active Directory is supported. LDAP is the industry standard for unified user management and authentication, spanning multiple application domains across multiple sites. By integrating DBmail with LDAP, email user and alias management can be performed easily and transparently from within the chosen LDAP user management environment.

Other uses CDB disambiguation lowercase cdb , short for constant database , refers to both a Library computing library and data format created by Daniel J. Bernstein . cdb acts as an on disk associative array , mapping keys to values, and allows multiple values to be stored for a single key. A constant database allows for only two operations creation and reading. Both operations are designed to be very fast and highly reliable. Since the database does not change while it is in use, multiple processes can access a single database without locking. Additionally, since all modifications are actually the creation of a replacement database, it can take advantage of UNIX filesystem semantics to provide a guarantee of reliability. Keys, values, and total database size have no arbitrary limits, though the use of 4 byte offsets restricts it to 4 gigabytes or smaller. cdb is used by djbdns , fastforward , mess822 , qmail and ucspi tcp to provide highly efficient, reliable, and simple data access. Structure A database contains an entire data set e.g. a single associative array in a single computer file . It consists of three parts a fixed size header, data, and a set of hash table s. Lookups are designed for exact keys only, though other types of searches could be performed by scanning the entire database. Lookups are performed using the following algorithm Hash the key. Determine at which hash table and slot this Storage record record should be located. Test the indicated slot in the hash table. If the slot is empty, the record does not exist. Abort the search. If the slot s hash matches the key s hash, seek to the record. Read and compare the key. If it matches, the data has been found, so abort the search. The record is not in this slot. Proceed to the next slot, wrapping around to the beginning of the hash table if necessary. For lookups of keys multiple values, additional values may be found by simply resuming the search at the next slot. Format All numbers offsets, length ... more details
