You may have noticed a different kind of junk mail getting through your defences – the messages only contain images and this sort of junk can’t be stopped by the normal email defence systems which scan the text – there’s no text to scan!
Those of you using Windows Live Mail, or Hotmail if you haven’t changed over, can stop much of this junk by setting your mail inbox options to only allow mail from people on your Live Messenger contact list.
Those using Outlook, Outlook Express or Windows Live Mail desktop could make some rules to block the addresses from which all this junk is orginating. However, the spammers saw this possibility years ago and rarely use the same address more than once for a spam deluge. So that’s a waste of time.
Outlook users have Microsoft anti-spammers working hard all the time to develop new rules – a new definition file is installed as part of the Microsoft patch Tuesday updates each month. Sadly, lots of things can happen in a month .
For an interesting read of how Terry Zink, one of Microsoft’s anti-spam team, works out what is spam is what is not, what he has to do to create new anti-spam rules (e.g., read through about 25,000 junk emails to analyse the way text is written by junk mailers), and trends in the junk spamming world, you can add his blog to your feeds.
