What is it?

DBMail is a collection of programs that enables email to be stored in and retrieved from a database.

Read the INSTALL file for installation of DBMail.

Why is it useful?

  • it enables you to create mailboxes without the need of systemusers.

  • Email is more effeciently stored and therefore it can be inserted an retrieved much faster dan any regular system (DBMail is currently able to retrieve aprox. 250 mail messages per second)

  • It's scalable. You can run the dbmail programs on different servers talking to the same database(cluster). LDAP integration allows you to integrate with existing authentication backends, such as ActiveDirectory.

  • There's no need to maintain system users or write access to the filesystem. All this is done through the database.

Who created it?

DBMail was originally created by IC&S in the Netherlands.

Around 2003, Paul Stevens at NFG also joined the development team, initially to provide debian packaging, later to take over development of the 2.1 release. Aaron Stone also deserves special thanks for initiating the LDAP driver, maintaining the delivery chain and of course sieve support.

DBMail is now a community effort to create a fast, effecient and scalable database driven mailingsystem. Both IC&S and NFG are fully behind opensource and the GPL. Therefore DBMail has the GPL licence.

Paul provides commercial support for this product. For more information about this you can send an email to
