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*.
distribution). Changes from version 2.2.1 include:

* Use the sysconftool from courier-auth to merge config files.
* The courier* rc.d scripts now check that authdaemond is also set to
"YES" to ensure that authdaemond is running before the courier-imap
daemons are started.
* Support for the ACL IMAP extension (RFC 2086 as well as the 2nd draft
revision of the ACL specification) via shared maildirs.
* Bug fixes and improvements to MIME encoding.
