ClearMyMail failed to establish a connection between a customer's choice of ISP and the amount of spam they receive, but did name the UK's most spammed citizen, Exeter-based Colin Wells.
According to ClearMyMail, 44,000 spam emails heading for Wells's inbox are blocked each day, amounting to around 16 million a year.
At the height of the problem Wells, a workshop foreman for Stagecoach buses, was spending two hours a day deleting spam from his account, making the prospect of "taking a week's holiday a complete nightmare".
The UK's second most spammed individual, who also uses Orange as their ISP, is fortunate by comparison with just 13,578 daily junk messages.
The third, fourth and fifth most spammed British citizens get 12,428, 5,760 and 3,982 spam mails a day respectively.
