mail filter

Mail Filter was developed to be an email filter application. It requires you have your own domain, that you are using qmail for mail handling (although it might be possible to adapt it for others since it is just scripts) and that your domain host is the helpful type since it needs a entry in each email accounts .qmail file.

This Application expands the functionality of ArGoSoft Mail Server Pro (http://www.argosoft.com). It acts like a Server Extension plug-in and allows you to perform simple "actions" based on predefined "message rules" or "conditions".

The goal of this application is to provide your users with a SPAM and virus free email environment as well as add other mail server enhancements.

The MF Actions, such as mail forwarding, play sounds executing an applications and controlling the services can be created by using our friendly Administration Panel that has the look and feel of Outlook Expresss Message Rules dialog.

The Panel allows you to create complex tests on each email as they email passes through your server. Message rules can be applied to all emails or only to those that meet certain specifications set by you.

Actions can be combined to do many tasks from simply adding a sales message to the bottom of each email or forwarding a copy of every email to a backup server. Your choice. You simply check the choices that are to be applied to the rule.

Constrictor is a Python module for parsing, filtering, and delivering mail as a Mail Delivery Agent (like Procmail). Constrictor provides the functionality to easily write a MDA in Python rather than reading some configuration file of its own syntax.

This has the advantages that configurations are readable and self-explanatory (at least, to anyone who knows Python) and that users have the full flexibility of the Python language at their disposal. Constrictor has the ability to deliver to maildir and Unix mbox format mailboxes, as well as bounce, forward, or reject messages.

Constrictor is currently beta software, at best. Im always very leery of software that messes with my mail, since one runs the risk of not only losing messages but, potentially, bouncing mail to great embarassment and chagrin. That said, I am currently using Constrictor on my own mailbox full-time, but, as always, your mileage may vary.

Installation

Constrictor is a single Python module that should be placed either in the directory you intend to invoke your MDA from, or in your Python library directory. The only non-standard module it relies on is the spamd module from the SpamAssassin distribution (available at http://spamassassin.apache.org/full/2.6x/dist/contrib/spamd.py), and only then if you intend to use the "spamassassin()" function to filter your mail (the module is loaded only when that function is called). Constrictor should work on all versions of Python greater than 2.3; it has been tested primarily on 2.3.4, 2.3.5, 2.4.1.

The spamassassin() function connects to a (optionally specified) spamd server (it defaults to localhost). If you do not have a spamd server, you cannot use this function.

For Postfix and Sendmail, edit your ~/.forward to include "|/path/to/filter.py". For more information on invoking this script as an MDA,see your MTAs manual or ask your administrator.

· This release adds locking code to duplicate database (pickle file used to recognize duplicate messages) access.

eScan Web Mail Filter for Windows description
eScan Web & Mail Filter for Windows is a useful against threat of viruses, effective anti spyware & blocks Spam eScan Web and Mail Filter for Windows is useful against threat of viruses, effective anti spyware & blocks Spam.

eScan Web and Mail Filter for Windows is the latest offering from MicroWorld Technologies Inc. It offers a combination of features to help you fight the threat of viruses, set security policies for parental control over content accessed by your child. It guards against Internet misuse, block Spam and offensive mails and block PopUp Ads.

Here are some key features of "eScan Web & Mail Filter for Windows":

Advanced Content Matching Options
· The software should allow you to set advanced content matching options that search for restricted words in different parts of the web page, set number of times a restricted word occurs in a page before it is blocked, allow you to block page elements like images, applications, movie files, etc.

Restricted Phrase Checking For Spam Mails
· Spam mails are unsolicited junk mail. These have an enticing subject line like: deal of a lifetime; free your debts, etc. The words may occur in the body, header, and HTML tags of the e-mail.
Block Spammer
· Another way to beat a Spam is to refuse entry to e-mail IDs that are known Spammers.

EMail Attachment Control
· E-mails are an invaluable tool to send and receive information. But they provide a very easy way to send out company confidential information in the form of attachments. While e-mail themselves can carry only information, e-mail attachments are the real sources to leak valuable company information. The following features need to be present.

Archive EMails
· Software should allow system administrators to save into an archive folder, e-mails and attachments, sent or received by users in the network. The saved e-mails can then be browsed to see if the contents violate your security policy. At the same time, you should be able to exclude specific attachment types from being archived.

Pop Up Ad Filter
· Pop Up Ad is an advertisement that appears when you access or exit a web page. These are created and placed on web pages by advertisers or web site owners. Not all Pop Ups are unwanted. Some sites require you to fill a registration form or you may have clicked a link for information and it is displayed as Pop Up.

Privacy Protector
· Privacy is very important to you. Manually deleting history folders, cache, etc. does not ensure your privacy as others can still find out details of the sites you visited, files opened, etc. The Browser Clean Up! feature allows you to automatically run a schedule that removes all such traces from your system...

The Content Security software should broadly address the following issues.
· Control access to websites
· Control e-mail activity
· Control remote file modification
· Block Spammers e-mail ID and issue warnings and notifications
· If your organization is large, then you need to assign uniform global security policies that govern all machines in your network.
· Recommended features of good Content Security software are given below

Restricted words:
· Software should allow you to specify restricted words and phrases like: porn, xxx, etc. and add them to the restricted words list. Access to any URL or page, that has these words, should automatically be blocked.
· The software should also be intelligent enough, not to block or flag educational or medical sites. Many Content Security softwares, currently available in the market, have this crippling problem.

List of banned sites:
· Software should allow you to add URLs of banned sites. Access to these sites is immediately blocked. Some notorious sites like www.hustler.com, www.playboy.com, etc. do not change their names. Such known sites need to be blocked outright.

Banned IP:
· Websites can be accessed by entering the IP (Internet Protocol) number. The software should be able to translate the IP number to its website name and block access if it contains restricted words or is on the banned list.

Filter Category:
· The software should allow you to create category of filters for block and allow site. Sites related to the category can be listed there. For e.g. Pornography Category will have sites related to porn and all sites for this category are blocked. It should be possible to add or remove sites from block and allow category with a mouse click.
