Choosing an Anti-Spam Solution
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.
