The UK has made it into the top 10 for spam relaying countries, in joint ninth place alongside Russia and Italy.
For the period between January and March 2010, 3.1 per cent of global spam was relayed by sources from within the UK, according to a study from Sophos.
However, the US was the worst offender, relaying 13.1 per cent of spam, with India and Brazil in second and third place.
China, a country that has been under the cyber crime spotlight of late, did not even make it into the top 12, coming in 15th position.
"All eyes aren't so much on which countries are on the list, but the one which isn't," said Graham Cluley, senior technology consultant at Sophos, in a statement.
"China has earnt itself a bad reputation in many country's eyes for being the launch pad of targeted attacks against foreign companies and government networks, but at least in the last 12 months they can demonstrate that the proportion of spam relayed by their computers has steadily reduced," the security expert added.
Despite this, Asia was still the dominant continent for spam relaying, with 33.7 per cent. Europe followed on 31.2 per cent, almost double the 16.9 per cent from North America in third.
Nearly all (97 per cent) of email received by business email servers across the world is spam, the Sophos study also showed.
