SPAM Filter services

Whether you choose our standard mail platform, our Microsoft Exchange solution, or choose to run your own server - we can provide our SPAM Filter service as an addition. We have spent considerable time refining our system so that you receive less junk mail. Our filter has many rules which carefully judge whether the mail is junk or not. Using industry standards, we ensure that we don't falsely identify real mail as SPAM with an exceptionally high reliability rate.

We have based our SPAM Filter service on leading competitors such as Symantec, SPAM Titan and more. We built our SPAM Filter with some key benefits in mind:
  • Verify the recipient exists before accepting the mail
    • This reduces processing of machine by ensuring the recipient is valid before comparing it to many more rules to see if it is SPAM
    • This reduces the amount of mail delivery failures generated from "spammers" sending thousands of mail with a forged mail from and a random to address
  • Verify the sender is valid before accepting the mail
    • Our server attempts to verify the sender by looking up the server for the sender and checking the email address is valid on their machine
    • This ensures the sender is really valid, which cuts out thousands of mails which have a completely forged "from" address
  • Scan the mail for any known virus infections
    • We use Clam AV to scan our mails once they have been 'accepted' for delivery. If a known virus is detected it is deleted
  • Scan the mail against a set of rules (updated daily) to gauge its score
A score determines whether we judge the mail to be SPAM or not. The higher the score the higher the chance it is SPAM Rules are provided through SpamAssassin and are updated on a daily basis to ensure the SPAM Filter is kept up to date.

The process described above, ensures that we very carefully check every single mail and ensures that we don't reject a genuine mail. At the same time, our system works as hard as possible to scrutinise the mail to see if it's junk mail. Blocking over a million SPAM mails every month, we are confident that taking up our SPAM filtering service will reduce the amount of junk you receive. We now display live information on our homepage - showing how many SPAM mails we have blocked and can provide you with statistics to demonstrate the same for just your domain.
