The Courier IMAP server is a fast, scalable, enterprise IMAP server
|
|
that uses Maildirs. Many E-mail service providers use the Courier IMAP
|
|
server to easy handle hundreds of thousands of mail accounts. With its
|
|
built-in IMAP and POP3 aggregation proxy, the Courier IMAP server has
|
|
practically infinite horizontal scalability. In a proxy configuration,
|
|
a pool of Courier servers service initial IMAP and POP3 connections
|
|
from clients. They wait to receive the client's log in request, look
|
|
up the server that actually holds this mail account's mailbox, and
|
|
establish a proxy connection to the server, all in a single, seamless
|
|
process. Mail accounts can be moved between different servers, to
|
|
achieve optimum resource usage.
