Fast and scalable sql based email services

Storage of mail messages in a relational database

Frontends: IMAP4, POP3, ManageSieve, LMTP

Backends: MySQL, PostgreSQL, Oracle, and SQLite

What are the advantages?

Scalability
Dbmail is as scalable as the database system used for storage.
Manageability
Dbmail can be managed by updating the relational database or directory service - without shell access.
Speed
Dbmail uses very efficient, database specific queries for retrieving mail information.
Security
Dbmail doesn't require filesystem access. It's as secure as the database and directory server used.
Flexibility.
Changes in a Dbmail system (adding of users, changing passwords etc.) are effective immediately. Users can be stored in the database, or managed separately in an LDAP server such as OpenLDAP or Active Directory.
