SquirrelMail is a standards-based webmail package written in PHP.
It includes built-in pure PHP support for the IMAP and SMTP protocols,
and all pages render in pure HTML 4.0 (with no Javascript required) for
maximum compatibility across browsers. It has very few requirements
and is very easy to configure and install. SquirrelMail has a all
the functionality you would want from an email client, including
strong MIME support, address books, and folder manipulation
PGPsendmail is a drop-in wrapper for the standard sendmail programme
which resides as /usr/sbin/sendmail on most Unix systems. It allows the
automatic encryption of outgoing messages by using the recipient's PGP
public keys. It does *not* provide for automatic decryption of incoming
messages: such a feature would necessarily involve compromising your
passphrase. However, it can provide for automatic signing of outgoing
messages by using PGPdaemon.
Rate-limited autoresponder for qmail:
- Limits rate of automatic responses (defaults to a maximum of one
message every hour).
- Will not respond to nearly every type of mailing list or bulk email.
- Will not respond to bounce messages or MAILER-DAEMON.
- Bounces looping messages.
- Can insert the original subject into the response.
- Can copy original message into response.
- Can use links in the rate-limiting data directory to limit inode usage
to a single inode.
- Optional support for MySQL
Elmo (ELectronic Mail Operator) is an ncurses-based program for
receiving, filtering, reading, composing, and sending mail from a
character terminal. It speaks POP3 and SMTP and can work with
maildir or Berkeley-formatted mailboxes.
This version is a development version, but is rather stable, and
is known to work better than the stable version on FreeBSD 4.x.
Before running elmo, users should run elmoconf.pl to generate an
~/.elmorc file.
This extension will display the current status of your
IMAP quota in thunderbird's statusbar and will warn you
when you reach a configurable limit.
It only works with IMAP quotas and servers advertizing
the quota status via IMAP (the IMAP GETQUOTA command).
Some mail servers have disk quotas and will send email
when your mailbox reach its quota. That's not a real
IMAP quota system and the imap server might not advertize
it.
SpamAssassin is a mail filter which attempts to identify spam using text
analysis and several internet-based realtime blacklists.
Using its rule base, it uses a wide range of heuristic tests on mail
headers and body text to identify "spam", also known as unsolicited
commercial email.
Once identified, the mail can then be optionally tagged as spam for later
filtering using the user's own mail user-agent application.
Additional drop-in rule sets are available at
http://wiki.apache.org/spamassassin/CustomRulesets
ARPACK software is capable of solving large symmetric, nonsymmetric, and
generalized eigenproblems. The software is designed to compute a few (k)
eigenvalues with user-specified features, such as those of largest real part
or largest magnitude. Storage requirements are on the order of n*k locations,
and no auxiliary storage is required. A set of numerically orthogonal Schur
basis vectors for the desired k-dimensional eigen-space is computed.
Numerically accurate eigenvectors are available on request.
Calc is an interactive calculator which provides for easy large
numeric calculations, but which also can be easily programmed for
difficult or long calculations. It can accept a command line
argument, in which case it executes that single command and exits.
Otherwise, it enters interactive mode. There are a great number
of pre-defined functions. The calculator can calculate transcendental
functions, and accept and display numbers in real or exponential format.
The calculator also knows about complex numbers.
Chryzodus is a cross-platform graphical program drawing
beautiful and colorful chryzodes.
If you do not know what chryzodes are, take a look at
http://www.chryzode.org/. Then you will be able to explore
the world of chryzodes by yourself using Chryzodus.
But one does not even need to know much about chryzodes
to use Chryzodus and see beautiful images appear on the screen!
clRNG
a library for uniform random number generation in OpenCL.
Streams of random numbers act as virtual random number generators.
They can be created on the host computer in unlimited numbers, and
then used either on the host or on computing devices by work items
to generate random numbers. Each stream also has equally-spaced
substreams, which are occasionally useful. The API is currently
implemented for four different RNGs, namely the MRG31k3p, MRG32k3a,
LFSR113 and Philox-4x32-10 generators.
