Teapop

Teapop is a POP3 server designed for virtual hosting. It allows separate configurations for different domains, and can look up authentication and mailbox info from databases. It supports mbox and maildir formats, and both PostgreSQL and MySQL.

Documentation for teapop is somewhat poor, but it is quite flexible.

Using Teapop with MySQL
To use Teapop with MySQL, you need to create a database table that Teapop can use to retrieve each user's password and the location of their mailbox. The table must contain at least a column with the user's name (the name can be specified in the teapop configuration file) and a column called "active" which must contain the value "1" for users that are allowed to login.

Then, in /etc/teapop/teapop.passwd, add a line like the following:



These fields are as follows:


 * domain
 * the domain name used by the user when logging in, or "empty" if the user doesn't use a domain name


 * dir
 * the directory within which mailboxes can be found


 * hash
 * the type of password returned by the database query: either 'plain' for plaintext passwords or 'md5' for md5 hashed passwords


 * uid,gid
 * the user and group used by the server to access the mailbox


 * host
 * database hostname


 * port
 * database port (may be left blank to use defaults)


 * dbname
 * name of database to user


 * dbuser,dbpass
 * username and password for authentication to database server


 * dbtable
 * table in the database to query


 * usercol
 * name of the column in the database table that contains the user's username (without the domain name part, if any is supplied)


 * pass
 * SQL expression that returns the user's password


 * box
 * SQL expression that returns the name of the user's mailbox within the "dir" directory. If the mailbox is in maildir format, must end with a '/'.  Note that as this may be an expression, the '/' may be added automatically, e.g. by using.
