It has been almost a year since our last SpamTitan status update and since then the number of emails that our SpamTitan cluster has processed has nearly doubled. To date our cluster has now examined over 135 million emails as can be seen from the chart below.
The overall percentage of clean messages has dropped from 36.8% to 35.7%. This indicates an even greater percentage of change over the past 11 months since these percentages take into account all of the messages that have been filtered to date.
If you compare this latest graph to the one prior you’ll also notice a reduction in RBL rejections. This is just a symptom of the messages being tagged as spam earlier in the filtering process because you can also see an increase in other front line rejections (SPF, HELO verification, greylisting, etc.). Messages filtered out at this stage would never get to the RBL rejection stage.
If you’ve been looking for more effective spam filtering we highly recommend giving our SpamTitan filtering a try. We’re still offering a 30 day free trial for all domains along with very simple and affordable $1.00 per address per month pricing after the trial period. Our SpamTitan cluster doesn’t just stop at spam filtering though. It also provides redundancy through spooling (queuing) of your email if your mail server is offline for any reason. This is a great feature for many of our clients whom prefer to operate their own local mail servers but require additional redundancy. Don’t hesitate to submit a ticket and request your free trial!
