Spam (unsolicited commercial e-mail) accounts for 35% of all messages and is rapidly increasing. 1 in 150 messages contains a virus, costing many billions of dollars around the world every year.

At JKAhosting, we take this very seriously. Therefore we use the latest AntiVirus and AntiSpam filters on our servers. Every web hosting account comes with complete SPAM protection using three different antiSpam systems (Mailscanner™, SpamAssassin™, and user definable rules-based spam filtering). The use of these various systems is designed to help you eliminate and remove up-to 98% of junk mail and viruses from your inbox.

Each email is checked by this filtering service which determines if the email is from a known spam source and if it contains any known viruses. The service gets information from many spam detecting and filtering networks so it can perform reliably. We catch around 95% of all incoming spam and over 98% of all viruses.

How does it work?

Our Spam Filter solution works to minimize the damage spam does to your business. The spam filter system scans every email sent to your account verifying the legitimacy of the email and determining the likelihood of the email containing spam. The system is deployed and administered on the mail server and managed by us ensuring there is no administrative overhead for your organization. The anti spam application works to identify spam emails before they reach your email box. Emails are scanned using our internal spam detection and filtering network and SpamAssassin™ a server based mail filtering system. Furthermore, an additional layer of Spam protection can be utilized from enabling the custom spam filters available from your control panel. This multi-pronged approach ensures maximum efficiency in reducing spam to your email box and can reduce spam levels by up-to 98%. Depending on your specific requirements the spam filter can manage email identified as spam in one of two ways:

  1. Automatic Deletion
    Once a particular email has been identified as spam it can automatically be deleted ensuring your staff are never inconvenienced by spam in the workplace. The emails are erased by the mail server and are never delivered to the end user dramatically reducing the presence of spam in your mail box.
  2. Automatic Tagging and Filtering
    The filtering application can be set to automatically tag suspected spam emails, once tagged the email will be delivered to the end user where the Email Programme (such as Microsoft Outlook or Outlook Express) will identify the tag and move the email to your junk folder. In this way emails are never lost but are simply relocated to the users junk folder. The user is then able to browse through the folder on a daily or weekly basis retrieving any emails that maybe of interest or use.

Benefits of Spam Filter

  • Fully managed spam prevention system, minimising administrative overhead for your organisation,
  • Constant checks for consistent spammers against an independent database of identified spammers,
  • Scans email at the mail server, therefore emails identified as spam need never reach your desktop,
  • Real-time detection and identification of suspected emails,
  • Scalability - from 1 to thousands of mailboxes!

The spam-identification tactics used include:

  • header analysis: spammers use a number of tricks to mask their identities, fool you into thinking they've sent a valid mail, or fool you into thinking you must have subscribed at some stage. Our Spam filters tries to spot these.

  • text analysis: again, spam mails often have a characteristic style (to put it politely), and some characteristic disclaimers and CYA text. Our Spam filters can spot these, too.

  • blacklists: SpamAssassin™ supports many useful existing blacklists, such as mail-abuse.org, ordb.org or others.
