Filtering Spam on Microsoft Exchange Mail Server
Exchange Mail Server - How to Filter Spam
By: Jane Y. Whigmore
Increasing threat from spam mails raises the need to monitor and remove illegitimate messages, thus ensuring proper functioning of the Microsoft Exchange system.
Mail spam adds trouble and decreases productivity and is a major threat to todays business world . Companies get tons of indecent, deceptive and irking e-mails in bulk regularly. Spam is the word most commonly used to express discarded, unwanted and promotional mails. It is not an acronym so it does not really denote something. Actually, a spam e-mail is usually a commercial mail sent to the recipients who did not request any kind of information from the company or the individual sending it.
Being bombarded with huge volum of unwanted e-mails with commercial content can cost businesses and individuals lots of resources and time while sorting and deleting unsolicited messages from the legitimate messages. This hinders an effective organisation and generates frustrated employees.
Deleting spam is a time consuming process, email server up-time and performance suffers, and your network faces a security risk from malevolent messages. Added to that, a company also risk that spam e-mails causes harm to systems and network that cannot be repaired which means disorder, work loss and increased costs.
The only measure against the spam threat ensuring total security and protection is professional assistance. Thus, the server should be shielded to assure that all the passing information is filtered and fire-walled against spam. Typically, a server spam filter is a software application that scrutinizes the incoming messages, spotting spam on the basis of pre-determined configurations while detaching the unwanted e-mail so that it never reaches the users inbox. And one of the widely used servers is that developed by Microsoft. Dubbed as Exchange Server, this Microsoft product makes e-mailing more speedy and resourceful.
Anti spam plugins for Microsoft Exchange is a great help filtering and avoiding spam mail. A server side spam filter enables users to automate the procedure to sort and remove spam at the server level i.e. before it reaches the internal network and each user’s personal computer. Automating is a suggested task as it saves the personal computer, and time of users in addition to the network from damage which can lead to data loss and downtime.
No anti-spam technology is perfect, periodically manual checking of all filtered messages by a network administrator is still needed to ensure that Exchange mail server is not blocking any legitimate e-mails.
London’s IP Expo Experienced Significant Microsoft Presence
Traditionally, the IP Expo in London is mostly attended by VMware representatives. This year, however, it seems that Microsoft has decided to take a more active participation in the said event which covers Internet Protocol, wireless technology, virtualization, managed hosting and cloud computing.
The said expo was significant for the software giant due to the recent launch of the Windows Server 2008 R2 Standard which included Hyper-V. It was also crucial because Microsoft is also set to roll out its new cloud platform called Azure.
During the event, the company rolled out a big announcement through its Virtualization Team Blog. Windows Server and Server Virtualization General Manager Mike Neil announced that Microsoft and Red Hat have already completed the certification of their virtualization programs. Clients are now provided with the ability to deploy the Microsoft Windows Server as well as the Enterprise Linux by Red Hat as well as a range of applications that are virtualized on products run by both companies with the knowledge that all these combined solutions will gain the support of both Microsoft and Red Hat. Microsoft is also set to certify additional third-party virtualization solutions in the future.
Microsoft Marketing Communications Director Patrick O’Rourke delivered a keynote speech at the expo. The speech was entitled, ‘The Cloud Continuum: Private and Public Clouds’ and talked about how companies can select the right virtualization solution that will suit their needs. The keynote was also illustrated through a number of case studies.
Other Microsoft Partners have also attended the expo in order to promote their most recent offerings. Citrix, for instance, was highly prominent in the Microsoft stand as it demonstrated the Citrix Essentials for Hyper-V. The said solution is designed to extend the capabilities of the Hyper-V and System Center Virtual Machine for improved scalability.
FCC Calls for Rules to Enforce Net Neutrality and Tame ISPs
Julius Genachowski, the Chairman of the Federal Communications Commission (FCC) has appealed to authorities to formulate net neutrality rules to govern the way in which internet service providers (ISPs) carry internet content. The FCC already has a set of policies on open internet, and the new rules will further enforce these strategies to prevent the ISPs from discriminating against certain content or applications when they carry the data across their networks.
The FCC’s call comes in the wake of fears that the US telecoms giants, who double up as the ISPs, can act as internet censors to stop the traffic from their competitors or block content they dislike. The FCC wants to prevent such misuse of powers by these companies, and wants new regulations for both fixed and mobile broadband operators. The Commission has enough reasons to be apprehensive, because the past years have seen cases where the ISPs have not supported the use of certain applications like VoIP services and peer-to-peer software; even a case of political content blocking has been noticed. All this reflects the need for stringent legislation that would enforce neutrality in the internet services.
Genachowski said internet should be used as a tool for economic growth, competition, innovation and democratic engagement. He added that the FCC was committed to working towards preserving the free and open nature of internet.
However, the legislation will face opposition from certain quarters, which believe restrictions to control the manner in which broadband providers (click for broadband
A Guide to Elite Optometric Equipment
Optometrists will find their vocation calls for far more than all their experience: because beyond this what they actually need above all is likely to be specialist equipment to aid them in serving up solutions as precisely as they can. We’ll examine three important items over the next paragraphs: concentrating on measurement, patient comfort, and equipment storage, and what to remember when purchasing each: be they new, used, refurbished or remanufactured.
Available to buy in multiple styles including handheld disposable, pocket, dynamic contour, non-contact and applanation models, the tonometer is the ideal way to measure intraocular pressure. Dependant upon your desires you might go with only one style or opt for an assortment of variant models. You’ll want to use only very high quality tonometers, so be careful when purchasing. Diagnosis becomes much simpler if you can boast both ease of use and accuracy with this class of optometry instruments.
Ensure that despite patients’ measurements they can all visit your practice without discomfort. You can do this without you having to sacrifice your capacity to position patients optimally to carry out their exam. There’s many opthalmologist exam chairs on the market perfectly capable of supporting any patient, from largest to shortest, which can be held in comfort in your preferred position.
All optometry equipment should be stored, and preferably somewhere that can be gotten at easily when needed. Usually this calls for a treatment cabinet boasting certain key features: flexible shelves, leveling glides in case of unsteady floors, and the like. Such cabinets are effortless to transport to any part of your practice that most needs their contents and to carry whatever else you’ll find that you use. Take care, however, that you order a cabinet that will not be too bulky to maneuver at moment’s notice. Three of the pieces of optometric equipment that can affect how well you do your job are the treatment cabinet, the examination chair, and the tonometer. Before you buy, you should ensure you know your exact needs. Uncomfortable gear will most very likely stymie you, but the simpler to use and the more ergonomic your instrumentation, the more proficient you’re likely to do in real life practice. The improvements this will manifest is really incredible…
So, as you’ll doubtlessly understand, the choices you make in terms of your equipment will be sure to have significant influence on how you perform in your job as a whole, and equally on the advancement of your entire practice.

Virgin Media Finds a Supporter in the ASA after Sky Registers a Complaint
A recent allegation was made by Sky Broadband against Virgin Media to the Advertising Standards Authority (ASA) regarding a national press ad released by Virgin Media. However, after investigations, the ASA did not find Virgin Media to be overstepping any regulations.
Virgin Media called its fibre optic broadband a future-proof technology and that it has been created giving due consideration to the needs of the internet. However, Sky Broadband found this to be inaccurate, and it raised questions saying that Virgin Media did not have the power to make such tall claims when it had no evidentiary support to back its statements. Sky also said that Virgin Media could not possibly have designed its fibre optic services to match the requirements of the internet because the internet itself is a comparatively newer concept than fibre optic internet.
Virgin Media also irked Sky (which uses copper wires) by the same advertisement which stated that service providers that use copper wire networks are unsuccessful in giving customers a service with low signal shrinkage, low signal distortion and a high data- transferring ability.
In spite of Sky’s accusations, the ASA concluded that consumers were smart enough to realize that Virgin Media is only promoting its fibre optic broadband and is not launching any invective against other service providers through its campaign. Therefore, Sky’s complaint was dismissed by the ASA on the grounds that the advertising was completely harmless. For an unbiased broadband comparison it’s worth referring to a dedicated broadband website, for consumers’ views on the service providers
Mobile Internet Is Vital for Freelancers
Trust me; I didn’t think I would be saying that a week ago. A week ago, I had barely even heard of mobile internet, never mind think that it would change the way that I did my work.
But that was before a freelance friend of mine managed to get their hands on a wireless dongle from broadbandgenie.co.uk (the piece of equipment needed to get mobile broadband). After using it for a few days he started raving about it, saying it was the greatest thing he had ever bought.
Eventually I gave his a try for a day, and loved it. Since then I have gone and bought my own (and got a free laptop with it) and consider it one of the best investments I have made for my freelance career to date.
Now I can take my work everywhere I go. I can work from anywhere in the
I know that my Blackberry is easier for quickly checking emails and the like. But for getting work done whilst away on trips, or wanting a change of scenery, a wireless dongle is a wonderful bit of kit.

What’s next for VoIP in the Future?
It seems that nothing can stop the runaway success of VoIP. Driven by lower cost faster internet connections Voice over IP has become one of the fastest-growing applications on the net. But apart from cheap calls in the UK, there are other factors which have contributed to this hugely popular way of making calls. There is clearly a trend toward more innovative and more mobile services and this looks likely to ensure that demand for Voice over IP continues to grow. It is estimated that there are already around four million VoIP UK users in the UK, excluding business subscriptions.
Industry insiders point to the emergence of ADSL broadband connections that do not require line rental for a conventional phone line (naked ADSL), and number portability between conventional and IP phone services as the two key things that will bring increase the profile of VoIP to new levels.
In fact such has been the impact of VoIP that some have suggested that it may not be long before users can dispose of their traditional landline telephones completely in favour of a internet phone.
Taking a more pragmatic view, there are issues that will need to be addressed before that can happen. In the United Kingdom Internet telephony providers like Vonage or VoIPTalk will have to review both security and ease of use, as well as continue to deliver a convenient and financially viable service. They certainly offer cheap calls already but, what else do they need to do to ensure a bright future for VoIP?
As the Internet is a network open to everyone the VoIP traffic is no more immune from attack than any other data. Security is an issue for many users, particularly in the business community and the means to increase protection for users would be a welcome step in securing the long-term future of VoIP.
The ease of use issue may not remain a hindrance to development now that handsets that work on mobile networks and, via WiFi or Bluetooth links, over VoIP are now taking their place in the shops. This raises the prospect of using reduced rate VoIP services at home, in the office or at a WiFi hotspot, but still retaining the flexibility of mobile coverage when out and about.
Some VoIP companies are now selling these handsets, and have set up joint arrangements with wireless hotspots so that their subscribers can make and receive calls when out and about without the need for a PC.
Expect to see some of the restrictions of such handsets i.e. difficulties in hotspots that use web pages for authentication to be addressed any time now.
The advance of newer networking technologies will further reduce the distance between fixed, mobile and VoIP services. Wireless broadband services, in particular WiMax, could create city-wide wireless hotspots, making it possible to make mobile VoIP calls in much wider areas.
Greater Gaming Notebook Saturation Great for Buyers
Do you recall when gaming portables were a specialist breed? Even though they didn’t shift a big amount they still brought in the most in relation to other types of laptop. The most sought after laptop computers were the ones that were too pricey to consider purchasing. Obviously as they were so advanced they were the best laptops in relation to performance. They would create a lot of excitement but I don’t think loads of people would go out and buy laptops at high prices. As the large computer companies distinguish the potential revenues in gaming laptops, the business is shifting.
These laptop computers have a particular price point and these companies are aware they don’t have to be price aggressively in this sector. As the profit potential on mid range laptop computers have gotten so tiny, manufacturing specialized gaming laptop computers is one plan to regain a higher gross margin. I am pretty certain that people would buy laptops if marketed to everyone by these massive companies. I don’t know what this will do to smaller resellers but it will have a negative effect on them. Really what I see taking place here is that the larger companies cutting prices in the beginning to cut out the competition from smaller system builders. I reckon the ignorant automatically feel at ease by purchasing from a manufacturer they are aware of.
The laptop computers hitting the market place are proving to be the best laptops ever seen. This surely should give some hope to the littler competitors. From time to time the smaller resellers can offer the latest parts quicker and hence supply better specs too. Normally lots of comparisons of the tech specs will be carried out and the techies can decide what the superior laptop really is. For these types of consumers, the tech specs of a system normally mean more than the looks of it.
This is all great from the purchasers position. Better technology will be increasingly accessible in the future for the majority of buyers as it will act to push costs down further. I think even industry analysts would have a difficult time seeing where the market is headed. New laptop launches should prolong expensive prices. Strong Competition normally drives companies to do more and provide greater value so that appears promising.

Bill Gates Made Data Recovery Easy
Bill gates provided a ready made option in Microsoft windows, which is very useful for data recovery.
Several time we make mistakes unknowingly and we lost our data, then we need to recover the data. There are so many data recovery solutions available but most of them are very costly. There may be a very easy way for data recovery.
To use data recovery you can back up your files to CDs, DVDs, external hard drives, other internal hard drives, tape drives, etc. They all work, it’s just that each media choice has it’s own pros and cons regarding ease of use, data storage capacity, and so on. It hardly matter what media you choose for data recovery but the important thing is that it should work.
There are several good backup programs that are very much useful for data recovery job, but Bill gates provided one very good option to do data recovery very easily. Most Microsoft Windows users have a great backup program included with their operating software. If you are a Windows XP user that program is called NT Backup. If it’s not already installed on your computer insert your Windows CD, find the folder titled ValueAdd\MSFT\ntbackup, and run the program in that folder called ntbackup.msi. It will set up the backup software for use on your computer in no time and you will even have simple to use wizards that will walk you through doing file backups and restores simply and easily.
After properly installing the software you can be prepapered for any time data recovery. Probably this is the easiest way to recover your data. Whenever you will need this trick will work and the cost of data recovery will be negligible.
