We think we have always been good at minimizing the effects of spam on our clients through mail filtering on our firewalls. It is always hard to measure effectiveness, as every client has a different spam profile, and we can only measure what’s been rejected and accepted, not whether we were accurate or not. All we know when working with clients is how much spam a client was receiving prior to us fixing their system and how much we are detecting and preventing – and the feedback has always been great in terms of reduction of spam being received.
What we hear anecdotally is that spam is on the rise, and we are seeing more spam being detected. Stats from Spamcop.net show the level of increase and 12 month trend. To increase the effectiveness of our spam detection we are rolling out two new methods of detection and prevention. The first is greylisting and the other is OCR of images. We will be rolling these updates out as required and as firewalls are upgraded.
So if you have spam issues, contact Greig McGill, Michael Pook or Andrew Johnson.
