Abook is a text-based addressbook program designed to use with mutt mail
client. Abook runs on Linux, FreeBSD and some other UNIXes.
The amavis-logwatch(1) utility is an Amavisd-new log parser
that produces summaries, details, and statistics regarding
the operation of Amavisd-new (henceforth, simply called Amavis).
A key feature of amavis-logwatch is its ability to produce
a very wide range of reports with data grouped and sorted as
much as possible to reduce noise and highlight patterns. Brief
summary reports provide a quick overview of general Amavis
operations and message delivery, calling out warnings that
may require attention. Detailed reports provide easy to scan,
hierarchically-arranged and organized information, with as
much or little detail as desired.
The Anomy sanitizer is what most people would call
"an email virus scanner". The most important jobs that the sanitizer
can do for you - it can scan email attachments for viruses.
Other things it can do:
- Disable potentially dangerous HTML code, such as javascript,
within incoming email.
- Protect you from email-based break-in attempts which exploit
bugs in common email programs (Outlook, Eudora, Pine, ...).
- Block or "mangle" attachments based on their file names.
This way if you don't need to recieve e.g. visual basic scripts,
then you don't have to worry about the security risk they imply
(the ILOVEYOU virus was a visual basic program).
This lets you protect yourself and your users from whole
classes of attacks, instead of blocking individual exploits.
CRM114 is a system to examine incoming e-mail, system log streams,
data files or other data streams, and to sort, filter, or alter the
incoming files or data streams according to the user's wildest
desires. Criteria for categorization of data can be by satisfaction
of regexes, by sparse binary polynomial matching with a Bayesian
Chain Rule evaluator, or by other means. Accuracy of the SBPH/BCR
classifier has been seen in excess of 99 per cent, for 1/4 megabyte
of learning text. In other words, CRM114 learns, and it learns fast.
DavMail POP/IMAP/SMTP/Caldav/Carddav/LDAP Exchange Gateway
DavMail is a POP/IMAP/SMTP/Caldav/Carddav/LDAP exchange gateway
allowing users to use any mail/calendar client (e.g. Thunderbird
with Lightning or Apple iCal) with an Exchange server, even from
the internet or behind a firewall through Outlook Web Access.
This software is supposed to work as a "reference implementation" of the
suggested "whoson" internet protocol. The protocol is expected to be
employed on "spam relay protected" mail servers to allow traveling
customers still send their email via the protected server. For this, a
realtime database of "temporarily trusted" IP addresses is maintained by
a special daemon program. The database may be filled by, e.g. POP/IMAP
servers, and used by SMTP server. Another possible use of the protocol
is to have the database filled by RADIUS/TACACS server for all dialup
clients, and SMTP server using it to put the user identity into the
"Received" header along with the source IP address. The protocol itself
is defined in a separate document "whoson.txt".
This is an implementation of DomainKeys Identified Mail (DKIM) draft standard
for the Postfix mail transfer agent. DKIM is a scheme to sign and verify
e-mail messages on a per-domain basis.
Details regarding the protocol and other issues related to the draft standard
can be found at http://mipassoc.org/dkim/.
DSPAM (as in De-Spam) is an open-source project to create a new kind
of anti-spam mechanism, and is currently effective as both a
server-side agent for UNIX email servers and a developer's library
for mail clients, other anti-spam tools, and similar projects
requiring drop-in spam filtering.
esmtp is a user configurable relay-only Mail Transfer Agent
(MTA) with a sendmail compatible syntax. It's based on libESMTP
supporting the AUTH (including the CRAM-MD5 and NTLM SASL
mechanisms) and the StartTLS SMTP extensions.
These are the esmtp features:
* fully sendmail command line compatible,
* supports the AUTH SMTP extension, with the CRAM-MD5 and
* NTLM SASL mechanisms,
* support the StartTLS SMTP extension,
* requires no administration privileges,
* individual user configuration,
* does not receive mail, expand aliases or manage a queue.
Asmail is a "mail-checker" like xbiff, but with the Afterstep
look & feel. It indicates the status of your mailbox.
It can be put in the Wharf, execute a program on incoming mail,
execute a program upon mouseclick, show animations and more...
