E-Mail Service Filters Microsoft Outlook Virus Vulnerabilities and Spam

Glenview, IL (PRWEB) April 16, 2004

Most of the popular mailserver virus scanners won’t be able catch new viruses in the near future. You may spend $ 10,000 on a virus scanner, only to find out that it lets viruses through unscanned.

A vulnerability is a security flaw in a program. You may have heard about some of the more common mail client vulnerabilities, such as the Outlook “MIME Headers” vulnerability (where a virus can be run automatically with certain versions of Outlook). While these are bad, a standard mail-server virus scanner will catch viruses that exploit these vulnerabilities.

However, there is another serious type of vulnerability that has recently been discovered: mail server vulnerabilities that allow viruses to bypass mailserver virus scanners! For example, the “Outlook ‘MIME segment in MIME preamble’ vulnerability causes Outlook to see viruses that don’t actually exist in an email. In this case, a mail client (or mailserver virus scanner) that properly decodes the email will not see an attachment. However, Outlook will incorrectly see an attachment.

When a virus uses this type of vulnerability, it will bypass a standard mail-server virus scanner, and get delivered to the recipient! That’s why you should use ActivatorMail: it detects these vulnerabilities! ActivatorMail will be able to catch new viruses that use the vulnerabilities, where standard mailserver virus scanners won’t be able to. Do you really want to buy a mailserver virus scanner that can’t catch new viruses? Now you can just use ActivatorMail filtering instead.

An Automated Anti-Virus Protection, Filters and SPAM Protection was installed on all servers from http://www.hostghost.biz hosting network.

Fremont, CA (PRWEB) July 15, 2004 –


After numerous requests by many web hosting customers for the addition of Anti-Virus Protection, Filters and SPAM Protection for e-mail accounts, we have added them on all servers form our hosting network in the beginning of the last week.

Anti-Virus protection is automatic for all our SMTP and POP3 servers. In case that the computer of any of web hosting customer who uses our SMTP and/or POP3 servers, is infected by a virus, which spreads by e-mail, then our anti-virus protection will not allow the virus to be send through our SMTP server. The same applies to receiving e-mail through our POP3 server. When receiving e-mail from our POP3 servers, the messages, which contain viruses, will be blocked by the anti-virus protection of our POP3 server and will not be delivered to the web hosting customer. You should all be aware of the fact that any anti-virus protection can save you only from existing and recognized viruses. This is so, because unfortunately the people who create and spread viruses over the world have the last say on this issue.

http://www.hostghost.biz is happy to announce that 2 new e-mail features have been added to the Web Hosting Control Panel – “Mail Filters” and “Spam Protection”. Both have been added and can be accessed through the “E-mail Manager” section of the Control Panel. “Mail Filters” and “Spam Protection” can easily be configured using the option available Web Hosting Control Panel options to find and redirect or delete unwanted e-mail messages. The vast diversity of the features’ options guarantees almost 100% spam protection. Since users can select the level of protection in the “Spam Protection” section, they can experiment with the appropriate level of spam protection they require, based on the results from changing from one level to another. “Mail Filters” is also a very powerful anti-spam tool. Users can set different mail rules, which can either delete or redirect unsolicited e-mail which do not match the user-defined rules. When entering the “Mail Filters” section, users can see all added mail rules, change their priorities, edit the existing rules, or delete a mail filter.

Email Magician 1.5 Offers 1,000 Spam Filters

March 4, 2002 – Email Magician 1.5 more than doubles the number of spam filters of previous versions. In this new version of YAV’s popular utility for Eudora® Mac, spam filters test for approximately 1,000 spam characteristics that may be present in incoming mail, thus keeping your mailboxes uncluttered. In addition to these built-in spam filters, the program also offers Spammer Address Collection, an option that tracks spammers (up to about 1,250) who may be targetting you in particular, and trashes their messages before they even hit the other spam filters.

This follows closely on the heels of version 1.4, that added the capability to export mailboxes to FileMaker Pro™ while stripping html tags. The price for Email Magician remains at $ 35 and registered users can upgrade for no charge.

By detecting who you correspond with regularly, Email Magician automatically creates filters, mailboxes, and address book entries for Eudora. The program also automates many tasks related to archiving email messages, and optimizing your Eudora folder. Email Magician has also introduced an “intelligent” Urgent Filter note-pad, where you jot down phrases and email addresses that tell Email Magician to override existing filters and, for example, gather all your “to do” items into a single mailbox for quick disposition.

Never make filters, mailboxes, or nicknames in Eudora again! Put spam in its proper place. Let Email Magician keep all your mailboxes clean. Email Magician can create hundreds of filters, mailboxes, and nicknames in the time it takes to manually construct a single filter.

SpamSolution.org publishes recipe for defeating Bayesian spam filters.

(PRWEB) September 10, 2003

Bayesian filters are all the rage. There probably isn’t a spam filter left that isn’t using some form of statistical method for filtering spam. But to be considered superior, it needs to be a Bayesian filter. Trevor Tompkins of spamsolution.org disagrees with this blanket acceptance of Bayesian filters. He has outlined problems with them in the past, and now has published a recipe for defeating them at the spamsolution.org web site. So how does one solve the problem of spam? Trevor says that you must use a form of authentication and permission granting, which is outlined in their published paper “Giving E-mail back to the users” at http://firstmonday.org.

Auto-Whitelisting Delivers Legitimate Emails Through AntiSpam Filters

Glenview, IL (PRWEB) April 22, 2004

Imagine for a moment if you sent someone an email, they could communicate straight back to you without the fear of loosing their email messages to capture by aggressive antispam filtering. Whitelists may be used to guarantee delivery right through antispam filters. ActivatorMail’s new ‘intelligent’ email servers automatically whitelist using this method, expediting delivery of legitimate emails. This unique auto-whitelisting is designed with the premise that if you send many messages TO [email protected], any message FROM [email protected] is most likely not to be spam.

ActivatorMail may be setup in minutes and works with any standard web browser or email client, like Outlook, Eudora, Netscape or any standard email server, like Microsoft Exchange, Unix/Linux SendMail, etc. The service includes aggressive antivirus scanning and there is no expensive software to purchase and install, saving thousands of dollars in up-front and ongoing expenses.

Industry analysts say money is being lost, customers are being lost and key opportunities are being missed because our best-laid spam efforts are mistakenly throwing the baby out with the bath water. Blocked legitimate email, or false positives, is costing U.S. businesses roughly $ 3.5 billion this year alone, according to a new study from San Francisco-based Ferris Research Inc.

In addition, internet service providers are blocking substantial amounts of permission-based emails, mistaking them for spam. ISPs failed to deliver 18.7% of opted-in emails sent to their subscribers between July 1 and December 31 2003, according to a study by email performance management company Return Path, Inc., New York. NetZero topped the list with the highest percentage of non-delivery at 37.7% of permission-based email, followed by SBC Global/Yahoo at 26.7% and Mac with 26.2%.

Activatormail whitelists may even be installed before hand, before services are ‘turned on’, to assure critical email deliveries right from the beginning.

Mississippi State University Filters E-Mail While Upholding Individual Freedoms

Ottawa, Ontario, Canada (PRWEB) May 3, 2005

Mississippi State University has evaluated and selected Roaring Penguin Software’s CanIt-PRO anti-spam solution to stop unwanted e-mail from reaching its campus. The solution now protects more than 20,000 students and staff at Mississippi State from the thousands of spam, virus, and malformed messages that hit the university’s mail servers every day.

Tim Griffin, Director of ITS Systems and Networks at Mississippi State, said, “We chose Roaring Penguin’s CanIt-PRO because it provides us with exactly the flexibility we need to combat junk e-mail. Over the past two years, we looked at a number of anti-spam solutions, but none allowed our end-users to individually customize filtering policies for their email addresses. Once we saw what CanIt-PRO offered, we knew we’d found the solution we’d been looking for.”

Mississippi State University extensively tested CanIt-PRO and chose the solution primarily for the level of configuration the product provides and for its stability and scalability. CanIt-PRO has enabled the university to create global filtering templates from which even non-technical users can select their preferred options and effectively filter their email. In addition, Mississippi State uses CanIt-PRO to give more tech-savvy users the ability to finely-tune their own filters to suit their personal wishes.

Griffin added, “The reason we needed flexibility in a filtering solution is that while some users would report that 90% of their inbox mail was spam, others told us that they weren’t having any problems. The spam wasn’t being delivered evenly across campus, so any solution we picked had to be able to understand and accommodate that. Also, we had to be very, very careful to preserve academic freedom.”

CanIt-PRO is ideal for campuses, ISPs and large organizations where global filtering policies must be balanced with individuals’ ability to have the final decision over what is and is not spam. CanIt™ products offer the industry’s most complete and flexible anti-spam and anti-virus solutions. They can be deployed in any enterprise e-mail environment, including on all Linux and UNIX servers. As a stand-alone gateway appliance, CanIt can protect e-mail environments running non-UNIX servers, such as Microsoft Exchange, Lotus Notes and Novell Groupwise. A trial version of CanIt or CanIt-PRO can be obtained at http://www.roaringpenguin.com/anti_spam/get_canit_request.php?id=msstate.

Anti-Spam Filters, ISPs, and the Law

(PRWEB) June 10, 2004

In a recent interview, Mr. Davey, one of the inventors of the eMstamp system had this to say: “I’m concerned that in the name of expediency [to block spam mail], we’re rushing headlong into a multi tiered Internet. I’m a small businessman so I quickly embraced the Internet as a way of leveling the playing field. Now with ISPs and hosting companies controlling our e-mail and signing on to mail reader, bonded sender, and authenticated user filtering schemes, we’re rushing headlong into a system where big companies dictate the content and source of our Internet communications.”

The paper describes mail filters and the areas of application. It explores some of the failings of filters and the costs associated with using filters at the MTA (Message Transfer Agent) level. MTAs are the computers that transfer messages over the Internet. They are run by ISPs and other commercial enterprises. The paper endorses the use of filters applied at the end user level by mail clients while raising concerns over MTA level filtering by ISPs.

ImagineNation proposes a simple alternative to filtering that puts a stop to spam mail at the source. It’s called the eMstamp system wherein MTAs buy credits in bulk and apply a given number to each message before sending. Incoming MTAs capture the applied credits for reuse in sending mail. This way only MTAs that are sending more messages than received, such as commercial and spammer MTAs, will need to buy credits. MTAs operated by regular e-mail providers like AOL, Yahoo, and Hotmail always have more incoming than outgoing mail so they never have to buy credits or charge users for sending mail.

About ImagineNation ImagineNation is small, diversified creator of specialty software. The company is currently evaluating avenues to commercialize the eMstamp system. Details on eMstamp and e-mail contact information is available at http://eMstamp.org .

Bagle Virus Riding on the Coattails of Spam; Deceiving Spam and Virus Filters

New York, NY (PRWEB) August 12, 2004

GIANT Company Software developers are working round the clock to make sure that their anti-spam software, Spam Inspector, is staying ahead of the latest form of the Bagle virus also now known as Bagle.al.

The newest version of this virus was first detected earlier this week and has proven to be successful in fooling virus and spam filtering software. Its known method of delivery is spam email oftentimes containing attached zip files. The email is sent from a “spoofed” address or a familiar address the virus copies from the infected computer, the subject lines are typically blank, and the message itself is nonspecific. The content is kept small purposely as it is more likely pass through content filtering software undetected. Once the email is opened a fraction of the code is installed onto the computer the rest is automatically downloaded from mainly overseas Web sites. As soon as the virus is on place it is capable of renaming existing files and downloading unwanted ones.

“Prior to the popularity of Spam, it would often take virus quite a bit of time to travel their targets. However, since the birth of spam viruses now have a faster more direct mode of transportation. Virus developers encrypt the spam with their latest affliction and it’s off and running” Ron Francyzk, GIANT Company Software. The only upside to this new method of delivery is that the virus also hits the radar a lot faster can often be extinguished before too much damage is done. “As soon as a virus hits our radar, we know that time is our own worst enemy. We have to move quickly to make sure that our customers’ computers remain secure ”, Andrew Newman, GIANT Company Software.

Even though that it is thought that this latest outbreak is going to be short lived, it’s just a matter of time before we see its next of kin hitting the networks. Email users who have anti-spam software installed are usually less likely to be victimized than unguarded email users but as Bagel has proved filters are not always foolproof. One of the many great features of Spam Inspector is that is it supported by a team of developers working persistently to make sure that the software stays in front of the latest virus and email scams. The software self-updates regularly even hourly if necessary without the user having to perform a single configuration.

Spam Inspector is designed to capture the most simplified and most complex forms of spam, with one of the highest levels of accuracy and lowest false/positive ratings available on the market. Spam Inspector has a global learning network of over a half-million users, also providing developers with useful data for maintaining its’ powerful engine and users with a continuous sense of security.

Extreme Spam Filtering – When Filters and Blacklists Are Not Enough.

(PRWEB) February 6, 2005

0Spam.com, a free anti-spam service, announces its new wave of features, tools, downloads, translations, and other major service improvements. By providing a smart and efficient anti-spam solution simple enough for home users and powerful enough for business users, 0Spam.com has grown its user base in the past 18 months to include thousands of satisfied users who are spared from millions of spams each month.

0Spam.com uses a CAPTCHA as a test to determine spam messages apart from legitimate E-mail. All mail is assumed spam unless determined otherwise by a series of user-defined whitelists, various global whitelist filters, and IP address checks. Messages that pass any of the whitelists are allowed to remain in the user’s inbox. Unauthorized messages require the sender to verify their E-mail address only once to show that their message is legitimate. Many users claim a 100% spam blocking accuracy rate.

Major features added since August 2003 include support for Yahoo, Hotmail, Gmail, and IMAP accounts; support for blind users; a whitelist specially designed for mailing lists and newsletters; homepage translations into Dutch, Spanish, and French; a virtual mail server which removes spam seconds before the user checks their E-mail; the ability for users to check their E-mail and view their Junk Mail folder at the same time, and more than twenty verification translations are now available including Chinese, Japanese, Russian, and Estonian.

0Spam.com Express, a downloadable add-on for Windows, makes it easy for new users to setup their account by automatically importing their E-mail account settings and address book into the 0Spam.com interface. Once installed, 0Spam.com Express sleeps in the Task Bar and intercepts spam between the user’s mail server and inbox, before the E-mail client has a chance to download it. A new site has been setup exclusively for 0Spam.com Express at http://www.0spamexpress.com.

Users may now take advantage of a new feature called Smart Language Detection which tells the 0Spam.com software to detect which language an E-mail was written in and sends back a verification message in the appropriate language. This is a key feature of the service which 0Spam.com has worked hard to make sure works properly. Planned upcoming features include a multi-dimensional DNS blacklist spam detection method and a smart mailing list detection algorithm.

In December 2003 0Spam.com has been accredited by the blind community to be the first anti-spam service that allows blind users to “see” the CAPTCHA number, used by many online services as a way of separating humans from computers or spammers. Here is how it works: the blind user is sent a verification message instructing them to visit the URL containing the image with distorted numbers. On that page there is an invisible hyperlink that only blind people can read with a screen reading program. The user clicks the link, enters their E-mail address, and the verification code is sent to them, which they can then enter into the first page containing the distorted image. Thanks to Grant Hardy of ACB Radio, for contributing his 28 minute review of 0Spam.com and how blind users can see the distorted verification code and protect their E-mail accounts from spam.
