We could eliminate SPAM tomorrow if...

We are all familiar with SPAM, its the huge volume of unsolicited crap that we have to wade through each day just to do our jobs, and yet there's no sign of it going away despite us all having the means to end it. So let's look at why we are all being subjected to the spam and then we'll look at why we don't end it when we all have the power to do so. 

The reason for SPAM

SPAM has three basic objectives and in order of volume, 

Current SPAM defences

And with these methods we can and do filter around 80% of your spam, but its never ever going to be 100% because SPAMmers spend a great deal of their time trying to circumvent these filters likewise costing us a great deal of money to continually adapt the filters for maximum effect. 

BUT, we do have the ability to stop the SPAM completely, 100% total removal of spam so why don't we? Well, quite simply we cannot because in this day and age everyone's an expert when of course they aren't. Using the current standards, and systems we could easily: 

So, it doesn't sound that hard does it? Well its not, but unfortunately as an ISP with many customers there are always going to be the few who effect the many as in many business models. No matter how much you promise your customers a spam free life, a minority of customers don't want to hear that fredbloggs inc doesn't meet the standards and/or is blacklisted and therefore cannot send them email, they just insist how important it is that fredbloggs inc can email email them. This creates a real problem for ISP's who technically want to kill spam as promised to their customer base but are also aware of the real world cost of dealing with ticket after ticket of 'I can't receive email from xxx' and the time and effort spent identifying the sender doesn't comply or is blacklisted then trying to explain that to the customer.  

So our approach, which has been adapted over the years is to offer three levels of protection: 

  1. No Filter - All email is accepted regardless. All Spam and Viruses are delivered untouched. 
  2. Basic Filter - Some filtering is done, but spam is still delivered with [SPAM] in the subject line allowing customers to filter that into a spam folder if required. Some antivirus protection is enabled. 
  3. Max Filter - All the above fully enabled and active both Anti-Spam and Anti-Virus. 

And as we expected the vast majority of business and corporate customers opt for the Max Filter, with only a very few opting for other options. The customers who opt for and stay with the Max Filter understand the issues and stand with us on the fight against spam. If a sender winds up blacklisted then they don't tell us, they tell the sender to sort it out. 

So what's the future? Well unfortunately as it stands with some ISP's favouring an easy life rather than deploying the available protections, with players like Microsoft and Google seemingly doing nothing to limit the spam they collectively originate, and with senders especially in the less advanced countries not able to configure even the very basic standard requirements we're going to be up to our armpits in spam for a good while to come but I do feel that things are changing as we're already seeing customers migrating to us solely for the benefits of our protection systems and that means we're doing it right. 

There are a number of articles on Blacklists, SFP, DKIM on our FAQ as well as the internet standards 1 RFC's. They are all technically orientated but available for anyone who's interested.
