Do Zebra's get more spam than Aardvarks ?

A new study reveals that the first letter of your email address might be crucial to the amount of spam you receive. Analysis of traffic logs of email received by a large UK ISP shows considerable disparity between the proportions of spam received by addresses with different first characters. This disparity is quite marked when only email addresses that appear to be 'real' are considered. The root cause is likely to be spammers using dictionary or Rumpelstiltskin attacks to guess valid email addresses.
