DBMail
Encyclopedia : D : DB : DBM : DBMail
DBMail is the name of a group of open source programs that enable the possiblilty of storing and retrieving mail messages from a database. Currently MySQL and PostgreSQL can be used as database backends.
The upcoming version 2.2 that is under development also supports SQLite, an embedded SQL database system, and ldap for storing userdata. Development and support of dbmail is done by [IC&S] and [NFG], two Dutch companies specializing in Linux development and support.
How does it work?
DBMail is made up of several components. A normal MTA (Postfix, SendMail, QMail, Exim) is used for accepting messages. The MTA hands the messages over to dbmail-smtp, using a pipe interface, or dbmail-lmtpd, using LMTP (Local Mail Transport Protocol). These programs take care of delivering the message into the database. Messages can be retrieved from the database using dbmail-pop3d, using the POP3 protocol, and dbmail-imapd, using the IMAP4Rev1 protocol.The whole email is stored in the database. That includes attachments. The DBMail programs do not have to touch the filesystem to retrieve or insert emails. User information is also stored in the database, so users do not need an account on the machines DBMail is running on.
