3.0.5 include:
* Implemented IMAP and POP3 proxy aggregator. With a proxy
aggregator, the mail accounts are split between multiple,
independent servers, with an IMAP/POP3 server running on each
individual server. A separate, proxy server sits in front and
accepts ordinary IMAP and POP3 connections. It reads the login
ID, determines which server the account is located on, connects
to the server, and logs in. Then, for the lifetime on the login
session the front-end server takes itself out of the loop, and
forwards all session traffic between the IMAP/POP3 client, and
the back-end server.
* Use courier-authlib for user authentication.
* IPv6 support.
* Minor bug fixes.
Please note when updating that the locations of the userdb files has
changed to be within the courier-authlib config directory, e.g.
/usr/pkg/etc/authlib/userdb*.

Courier-IMAP is a server that provides IMAP access to maildirs. This
|
|
IMAP server does NOT handle traditional mailbox files (/var/spool/mail,
|
|
and derivatives), it was written for the specific purpose of providing
|
|
IMAP access to maildirs.
|
|
|
|
"Maildir" is a directory-based mail storage format originally introduced
|
|
in the Qmail mail server, and adopted as an alternative mail storage
|
|
format by both Exim and Postfix. Courier-IMAP is popular on
|
|
Qmail/Exim/Postfix sites that are configured to use maildirs. The
|
|
primary advantage of maildirs is that multiple applications can access
|
|
the same maildir simultaneously without requiring any kind of locking
|
|
whatsoever. It is a faster and more efficient way to store mail. It
|
|
works particularly well over NFS, which has a long history of
|
|
locking-related woes.
|
|
|
|
This package differs from a vanilla Courier-IMAP installation in that
|
|
the files are installed at locations that more closely correspond to
|
|
a Courier installation.
