The request is based on the antiquated Electronic Communication Protection Act federal agencies can and do request and read email that is over 180 days old. The IRS response can be found at http://www.aclu.org/national-security/irs-response-warrantless-electronic-communications-foia-request. The IRS asserts that it can and will continue to make warrantless requests to ISPs to track down tax evasion. http://www.irs.gov/irm/part9/irm_09-004-006.html#d0e319.
