According to a report from IronPort called “2008 Internet Security Trends” it would appear that if 2007 was a bad year for spam – 2008 will break the record again!
One interesting statistic I found on the internet was from the European Unions Internal Market Commission, which estimates that junk email costs internet users 10billion Euros per year worldwide. For small to medium size businesses, this figure may seem like an incomprehensible fact. However, consider with me for one moment what happens in your business when just one spam email enters your company.
- Spam email finds its way through your company’s internet gateway. At this point the rogue email will take up a small percentage of the costly bandwidth allocated to your company by your ISP. If the spam e-mail contains an attachment, it will take up even more bandwidth. This reduces the bandwidth available for incoming/outgoing emails, surfing the internet, remote workers, VPN tunnels connecting branch offices… etc.
- The spam e-mail then penetrates your company’s mail server. If the rogue email is addressed to an invalid user, your company’s mail server will then attempt to reply to the spam sender saying the address has failed. This takes up more processing time and bandwidth. If the rogue email is addressed to a valid user, your mail server will deliver it into that user’s mailbox. Again, taking up more processing time. Remember, if your mail server is also your main domain server – it has other things to do with its time – like serve files and manage print jobs!
- The end user eventually receives the spam in their inbox. Inevitably, the user will then delete the email. However, when deleting it, due to human error, they often miss legitimate emails because they are caught in a sea of rogue ones. Also, sifting through spam emails takes up an employee’s time and the quality of the spam email is most likely undesirable.
The above is a rather crude view summarising the knock-on effect of one spam email entering your company. However, it’s worth remembering, as imagine the human and computer processing time taken up by 500 spam emails a day, not to mention the drain on bandwidth.
At RatwareUK, we have our own mail relay server. In a nut-shell, this means that spam can be filtered off-site and legitimate emails can then be passed through to your company, thus completely saving on a company’s bandwidth and human/computer processing times. Not only will our relay server eliminate spam, it will also scan all inbound emails for viruses!
If you are receiving 500 spam emails a day, knocking those out of the equation will definitely allow your server to perform daily tasks faster and save bandwidth. For more information, visit our Anti-Spam Services page.
