The Cyrus IMAP (Internet Message Access Protocol) server provides access to
personal mail and system-wide bulletin boards through the IMAP protocol.
The Cyrus IMAP server is a scaleable enterprise mail system designed for use
from small to large enterprise environments using standards-based
technologies.
A full Cyrus IMAP implementation allows a seamless mail and bulletin board
environment to be set up across multiple servers. It differs from other
IMAP server implementations in that it is run on "sealed" servers, where
users are not normally permitted to log in. The mailbox database is stored
in parts of the filesystem that are private to the Cyrus IMAP system. All
user access to mail is through software using the IMAP, POP3, or KPOP
protocols.
The private mailbox database design gives the server large advantages in
efficiency, scalability, and administratability. Multiple concurrent
read/write connections to the same mailbox are permitted. The server
supports access control lists on mailboxes and storage quotas on mailbox
hierarchies.

queue_repair features include:
- automatic, dynamic determination of UIDs and GIDs.
- automatic, dynamic determination of conf-split; can be overridden on the
commandline to change the conf-split of an existing queue without running a
parallel, temporary instance of qmail for queuelifetime. Just recompile and
stop qmail, run queue-repair, and restart qmail.
- automatic, dynamic determination of use of big-todo; can be overridden on the
commandline to change an existing queue as above.
- handles basic tasks like fixing a queue restored from backups, incorrect
ownership or permissions of directories and files, missing or extra split
subdirectories, unexpected files or other direntries, or creating a valid
queue from scratch.
- can run in repair or test (report-only) modes. The default is test mode.
Fetchmail is a full-featured IMAP/POP2/POP3/APOP/KPOP/ETRN/ODMR client with
easy configuration, daemon mode, forwarding via SMTP or local MDA, and
superior reply handling. It is used to handle intermittent email connections
by acting as a coupling that seamlessly batch forwards fetched mail from your
mail server to your local delivery system, allowing you to read it with your
favourite mail user agent. Fetchmail also includes useful spam filtering and
multi-user functions.
A typical use of fetchmail is to connect to your ISP's POP3 server,
downloading your mail into the INBOX on your local computer. You may then
read the mail, offline if you want, using pine, mutt, or any standard mail
user agent.
Xlbiff lets you preview new mail to decide if you want to read it
immediately. Regular xbiff lets you know when you have mail but not what
it is.
Xlbiff lurks in the background, monitoring your mailbox file. When
something shows up there, it invokes the scanCommand (MH's scan by
default), and displays the output in a window. If more mail comes in, it
scans again and resizes accordingly.
If you're a Berkeley mail person, you can set scanCommand to:
echo x | mail | grep "^.[NU]"
Or use the ``frm'' utility that is part of the Elm port as your
scanCommand. A simular utility is the ``fromwho'' package, posted to
comp.sources.unix volume 25.
vqadmin is a web based cgi program. It allows system administrators to
perform actions which require root access. The cgi is authenticated
using Apache style htpasswd files. Root access is required for adding
and deleting domains. A user based ACL provides control over what
actions can be performed, such as adding/deleting a domain. Accessing
user email account information to allow modification of user passwords
and quota's. Account service restrictions include enabling or disabling
of pop access, authentication based smtp relay control, courier-imap
access and sqwebmail access.
vqadmin and qmailadmin can work together. qmailadmin can be used to
allow users to administer thier own domains but not create new domains.
Creation or deletion of domains is normally associated with the
owner/admin's of the machine. vqadmin is for onwer/admin's or their
technical support staff.
Features
. Add / Delete virtual email domains.
. Change user passwords, quota's.
. Turn off account services such as pop, imap, web email or smtp relay.

The Visualization Toolkit (VTK) is an open-source, freely available software
system for 3D computer graphics, image processing and visualization. VTK
consists of a C++ class library and several interpreted interface layers
including Tcl/Tk, Java, and Python. Kitware, whose team created and continues
to extend the toolkit, offers professional support and consulting services for
VTK. VTK supports a wide variety of visualization algorithms including: scalar,
vector, tensor, texture, and volumetric methods; and advanced modeling
techniques such as: implicit modeling, polygon reduction, mesh smoothing,
cutting, contouring, and Delaunay triangulation. VTK has an extensive
information visualization framework, has a suite of 3D interaction widgets,
supports parallel processing, and integrates with various databases on GUI
toolkits such as Qt and Tk.

The SDPA (SemiDefinite Programming Algorithm) is a software package for
solving semidefinite program (SDP). It is based on a Mehrotra-type
predictor-corrector infeasible primal-dual interior-point method.
The SDPA handles the standard form SDP and its dual. It is implemented in C++
language utilizing the LAPACK for matrix computation. The SDPA incorporates
dynamic memory allocation and deallocation. So, the maximum size of an SDP
to be solved depends on the size of memory which users' computers install.
The SDPA enjoys the following features:
1. Callable library of the SDPA is available.
2. Efficient method for computing the search directions when an SDP
to be solved is large scale and sparse.
3. Block diagonal matrix structure and sparse matrix structure in
data matrices are available.
4. Some information on infeasibility of a semidefinite program to be solved
is provided.
