From 2007, Yahoo! provided Telecom's email service, which came under heavy criticism in early 2013 following a spam and phishing attack described as the biggest to have ever hit the country. Telecom and Yahoo! automatically reset tens of thousands of users' passwords. In April, Telecom announced that despite the issue, it would keep Yahoo! on as an email provider. Problems with Telecom's YahooXtra email continued into December 2013 and further into 2014 with the latest problems reported on 10 January.
