What is Email IP Blocking?
When a computer gets infected by a virus or worm, one of the likely results is that it becomes a spam bot. A spam bot is a computer under the control of cyber criminals which is continually sending out spam emails. In fact, an infected computer can send out hundreds or thousands of messages per hour as part of the spammer’s campaign. Over the past few years the quantity and overall percentage of spam has increased worldwide due to the proliferation of spam bots. No one at SLAC is immune to receiving these spam bot emails. At SLAC, we’ve implemented various methods to try to keep the spams from getting into your Inbox. On a typical day, 86% of the email received at SLAC are spam, or similarly invalid emails. Our email gateway software vendor, SophosLabs, strongly recommended we try their IP blocking service as a further step towards combating spam. This is a tool now widely used by many organizations. What they do is take various “DNS real time block lists” (DNSBLs) which are maintained
