Green IT – some simple ways to start March 24, 2008
Posted by charitysolutions in General, charities, charity IT, charity computers.add a comment
Last time we took a slightly cynical look at the mountain of green rhetoric we are all being subjected to these days. This week we are trying to cut through the marketing propaganda to give some suggestions that are practical and usable for all organisations – not just the huge ones with large budgets and resources.
First of all, forget about the hype and get back to basics. Remember the recycling mantra:
- - Reduce
- - Reuse
- - Recycle
Reduce is an easy one. Ensuring your computers and printers are shut down at night and not just left on standby will cut down on wasteful power consumption and immediately improve your green footprint. Remember to also switch off monitors when not in use – you can adjust the settings to switch off after a certain period of inactivity. Laptops (and even some PCs) can be set to go into a standby lower power mode if not used for a set period.
Reducing your office paper consumption is another hot issue. You could use less by using both sides and thinking before you print – do you really need ten copies in full colour? Using cheaper low-grade or recycled paper for general use and keeping high-quality paper usage to a minimum is another simple green solution.
Also, don’t forget that a lot of the simple greener changes you have probably already made at home can be carried over into the office – like using low energy bulbs and rechargeable batteries.
Reuse your IT equipment for as long as it is practical and economical. Upgrade only when extra features, speed or processing power is essential – or if the equipment is particularly old and “power hungry”. Some organisations use snazzy new computers that are far more powerful than necessary to run simple office applications. Older machines with less powerful processors could simply be fitted with additional memory or bigger hard disks to remain in service. If you do need a new computer, check the manufacturers website to how green (both in terms of power consumption and the components used) – and when choosing a manufacturer, consult independent organisations such as Greenpeace (www.greenpeace.org/electronics) who regularly monitor how well the main manufacturers are truly doing on the green front or visit the EPEAT website (www.epeat.net) where an increading number of PCs, notebooks and monitors are evaluated and scored according to set environmental criteria.
Think about refilling rather than discarding your printer cartridges. (But take care to check manufacturers warranty if your printer is new because sometimes use of third-party consumables can lead to warranty exclusions.) National companies such as Cartridge World have outlets across the UK where you can take your empty cartridges to be refilled. Or, if you prefer, you can also buy special kits and refill the cartridges yourself – though this can get messy and isn’t always particularly successful. By reusing your cartridges you will not only help save landfill space but you can save money.
Recycle! Under the European Union’s Waste Electrical and Electronic (WEEE) Directive, all manufacturers of electrical equipment are responsible for its environmentally friendly disposal, and the infrastructure required for collection. This allows old equipment to be reused and recycled where possible, with any potentially hazardous components properly disposed of. Your IT supplier may well have facilities in place to recycle your old equipment, if not consult your local council website or national one like www.recyclenow.co.uk.
Once again, the recycling efforts you probably make at home can be reproduced in the office. Don’t forget that not only can your waste paper be recycled, but cans, bottles, cardboard or even plastics. It might not be as easy or cheap (unlike the private house refuse collection facilities provided by councils, most commercial waste collectors will only provide recycling collection at an additional cost) but with a bit or organisation it can be done – and a bottle or can recycled from your office will save just as much energy and resources as one from home.
There are many green options available for smaller organisations and even small changes can make a difference to the environment – and also to your finances. Here are some links you may find useful:

Green IT – Is It Easy? March 17, 2008
Posted by charitysolutions in General, charities, charity computers.add a comment
Recycling your empty soft drink cans and glass bottles is by now second nature to most people. The introduction of kerbside collection has made recycling such a convenience that it almost goes against natural instincts to throw your recyclables in the ‘normal’ bin! But how many think of recycling and specifically Green IT at the office? As a Charity we know you are probably trying hard to do your bit, but if you are not a huge organisation it can be confusing to know where to start.
Put simply, Green IT is using your computing resources more efficiently. Some larger corporations are already taking steps to become more environmentally friendly. Quite apart from any concerns for our planet, they believe being green can reap benefits from cost savings to higher productivity. And of course better environmental credentials look very hip these days! But what does Green IT mean for the smaller organisations and what are some practical solutions?
These days there is much hype surrounding the Green IT issue. If you listened to all of it you would be scrapping your current IT for energy efficient PCs made from natural materials, ditching your servers for new high efficiency blade versions and encouraging your employees teleconference into work rather than drive. But if you take a step back and look at things more practically, it doesn’t take long to work out that (quite apart from the probably prohibitive costs involved) starting anew really isn’t an option that is cast-iron guaranteed to be more environmentally friendly long-term – particularly when you take into account the energy involved in producing all those new computers and shipping them all over the world, not to mention the cost, time & money to dispose of the old IT equipment that was still really working fine for you.
Don’t beat yourself up about the fact that you are not following every green recommendation or buying every new “greener” option. Remember that a lot of the people urging you to swap to those new greener options are not acting entirely out of concern for the planet – the sales of all that replacement kit does mean that those “go-green” pleas by the computer manufacturers are likely to be more than a little self-serving.
Hype aside, there are many small changes that you can make which when combined can still make a significant difference overall.
Next week we will go back to true green basics to look at some simple ways any organisation (however small) can make a difference.
Choosing an Anti-Spam Solution March 10, 2008
Posted by charitysolutions in General, charities, charity IT, charity computers.add a comment
In our last post we highlighted the need for an anti-spam solution for those organisations hosting their own mail server. In this post, we look at some of the options available, and some of the key things you need to take into account when choosing one for your orgainisation.
Anti-spam solutions can basically be broken down into two types – hosted and in-house.
Hosted solution
A hosted solution routes your mail to your chosen service provider who scans then delivers it your own mail server. Those wishing to contact you will do so via your usual email address and you continue to send email as normal. The only difference is that your anti-spam service will automatically check and process your email so that all you should receive is clean mail, free of spam and viruses. This will considerably cut down on the amount of mail that your mail server has to receive – and with up to 98% of all current emails being reported to be spam, that can make a considerable dent on the bandwidth you will need from your ISP.
Because a hosted solution provider is monitoring so many emails, it is best placed to see new spam trends developing and so is generally quickest to put new measures into place as new waves of spam arrive. It will also scan mail through multiple anti-virus solutions, from various vendors, so you can normally expect better protection.
Of course the best bit is you don’t have to worry about managing the spam yourself (also taking away the worry of added costs) – the anti-spam provider will assume these responsibilities on your behalf and, since you will normally be paying monthly or yearly for their services, it is in their best interest to make sure they do the job well!
In-House Solutions
An in-house solution is one that is installed at your own offices that you administer yourself (or get someone to do for you). The solution could be software-based (either one piece of central software that scans all emails – normally before they get to your mail server, or software that is installed on each person’s individual PC) or it can be a complete hardware “box” (containing its own software) that you plug into your network.
As in-house solutions require administering, you will need to take into account that managing the spam yourself will take time and may result in additional costs. Also, in-house systems must wait for updates to be released from the system’s manufacturer and so could be slower to be updated with the latest protection. Then there is human error, which means that there is the possibility that available updates and patches can go uninstalled.
But on the plus side, if you don’t need a complicated “bells and whistles” anti-spam solution, you may well be able to get an in-house solution cheaper than a hosted one. And, in time, you will have a much better idea of the type and level of spam that is coming into your organisation – and how to deal with it.
Do you need it to be customisable?
Depending on your specific needs, the level of customisation offered may be an important factor when choosing a solution. Some solutions (both hosted and in-house) are more customisable than others. For example, if your organisation’s area of working means that you receive legitimate messages containing on ‘spam-popular’ words (concerned with debt reduction or pharmaceutical names for example), you might ideally want to look for a solution that gives the ability to let emails containing words in those specific areas through rather than immediately label them as spam.
There are also solutions that allow more flexibility at user level – so that the spam protection for some email addresses can be set to be more or less sensitive than others. So it is wise to think whether your organizations areas of work or working methods mean that your requirements are not best covered by a “one size fits all” solution.
Whatever type of solution you choose, you do need to be aware that no anti-spam solution, whether hosted or in-house, will be 100% accurate. From time to time it is possible that a genuine email will be classified as spam, or that spam will sneak past the filter, so you will still need to check your quarantined spam area regularly – and if the solution you choose includes a simple way of doing this, it will make your life easier.
So, to summarise:
-
- Think about the emails your organisation receives and decide what level of customisation (if any) you are going to need from your anti-spam solution.
-
- Consider how much time and expertise you have within your organisation to administer an anti-spam solution.
-
- Work out the volume of email you receive and the proportion of the current total that is spam. If your ISP currently handles your mail, remember to factor in the additional bandwidth that will be taken up with spam when your ISP’s anti-spam protection is no longer in place – and any costs involved with that extra bandwidth. (Does your ISP charge you more if you go over a monthly limit?)
In the end, as with most things (particularly in IT!) it will probably come down to balancing the features you want or need with the budget and time you have at your disposal. But hopefully the information here will help you to make a more informed choice.

Your First Mail Server – Where Did All That Spam Come From? March 3, 2008
Posted by charitysolutions in General, charities, charity IT, charity computers.add a comment
In our role helping charities and NFPs to grow and manage their IT solutions, we are often asked to supply and install an “in-house” mail server.
Most organisations start off with their mail being hosted by an Internet Service Provider (ISP) such as Demon, Yahoo or AOL, but as they grow, they often wish to host their own mail server in order to give them more features and greater control and flexibility.
When we are asked to help, one of the things we stress to them is the need for some form of anti-spam protection to work alongside their new server. This sometimes comes as a bit of a surprise – the organisation may not have been particularly bothered with spam up to this point – and we have to explain why it is necessary. In part one of our entries on this topic, we cover some of the key reasons for this confusion.
We haven’t had a big problem with spam up to now
When using ISP hosted mail your ISP normally does a lot of work behind the scenes to ensure the integrity of your inbox. This may include:
- - Cross checking email destined for your inbox against a blacklist (a database of spam-offending domain names or IP addresses)
- - Checking incoming mail is being sent from a valid domain
- - Checking any attachments for dangerous content (for example certain file extensions or filenames known to be potentially dangerous)
- - Scanning for viruses
You may not be aware any of this ‘cleansing’ is happening but when you switch to an in-house mail server, mail will come directly to you rather than via your ISP, so this “invisible cleaning” service that has been protecting you up to now (even if you didn’t know it) will no longer be there.
We never publicise our email addresses so how will anyone know what they are to send spam to them?
Firstly, since email is such a common method of communication, not publicising email addresses really isn’t an option for most charities and NFPs these days.
Although it is fair to say the posting of your email address on various websites can make you more susceptible to spam, keeping a low profile will not necessarily ensure immunity. Spammers can be relentless in their pursuit – and have a veritable arsenal of tools to automate their work and make their lives easier.
Once you have your own domain name, details of the domain are available all over the internet to anyone who knows where to look – and will be obvious from your website address (www. mycharityname.org). Most organizations have some form of standard convention for allocating email names – and the spammers know all the common names and possible variations!
A common ploy is to send emails to numerous target addresses with slight variations of names – for example johnsmith@example.com, john.smith@ mycharityname.org or john_smith@ mycharityname.org. By sending to all possible variations, a spam address gatherer can easily find out which email addresses are likely to be real and “live” by the inclusion of seemingly innocuous coding in the spam message (a link to an online image for example) that sends them an alert when opened. Even if all users are scrupulous in never opening a message from unknown senders (often difficult in itself, since you can’t afford to ignore the emails of potential new donors or recipients), phishing can make an email message appear as if it was sent from a trusted known source, enticing the recipient to open the email and thereby notifying the spammer of a real live address.
OK – spam is annoying, but anti-spam solutions cost money – can’t we live with it?
Most e-mail spam began life as a relatively benign, but annoying, method of email advertising. Nowadays, much spam email contains malware – malicious programs and coding designed to destroy or compromise the security of your computers. Spam has taken on a more sinister and destructive guise.
Phishing can make an email message appear as if it was sent from a trusted known source, luring unwary recipients to potentially give up sensitive information.
Also, you can’t assume you will only receive a few spam emails a day. News of your email addresses will move out through the “spammer” community incredibly quickly and the spam will start to arrive the moment they receive your email addresses. Current statistics indicate that 90-99% of all email these days is spam. So even if your organisation only receives one of two “real” emails a day, these statistics indicate that without any spam protection, you are going to have to look through up to 99 messages of spam to find each real message. Quite apart from having to put up with the rather dubious content in the spam messages, do your people really have time to do this – and the focus not to miss the “real” messages amongst all that spam?
Basically, if you are going to run your own mail server, you are going to need some form of anti-spam solution to, at minimum, save your inboxes being overrun with junk mail. More seriously, your anti-spam can help save you network from the influx of potentially damaging malware by scanning and selectively delivering only safe items.
So now how do you choose what kind of anti spam solution will be best for your needs and budget? We will cover this in next week’s blog – but if you can’t wait that long just contact us (details on the About Us page) and we will be more than happy to discuss the options available with you.
