Good news today from Sophos as their quarterly report on the top 12 spam relaying countries did not include Canada. This marks a major shift as Canada ranked as high as second only a couple of years ago. While Sophos apparently attributes this to "the continued regulatory efforts as well as increased Internet safety vigilance by Canadian consumers," neither of those factors have much to do with it. Instead, it is the practice of most large Canadian ISPs who now block Port 25 that has led to the dramatic reduction in outgoing spam.
While this is an important milestone, it is important to note that the Sophos list only tracks the source computers of spam, not the actual sources of the spam. Canada remains home to several large spam groups that are likely sending their spam through other countries. With many other countries implementing tough anti-spam legislation, Canada is in danger of landing on another dubious list – those Western countries without anti-spam legislation – just as it exits the Sophos list.
