Among the 'offences' of which Pietersen, effectively sacked by England after their 2013/14 5-0 Ashes thrashing in Australia, was accused were "staring out the window" and "looking at his watch" during team meetings led by then coach Andy Flower.
It also said he whistled after being dismissed in the final Test in Sydney, and told his team-mates to get thicker skins when they complained of criticism of their performance in tweets by his friend Piers Morgan, the television interviewer, when England were 4-0 down in the Ashe.
Former England captain Vaughan derided the ECB document, telling Twitter he had "never read as much b------- in all my time".
Vaughan added: "Never laughed so much... England are 4-0 down in the Ashes and it's because of @piersmorgan tweet."
The ECB insisted the email received by the Cricinfo website was not the official dossier compiled by Flower, the subject of heavy criticism in Pietersen's book, but rather an internal email draft drawn up by their lawyers.
Pietersen brushed off the email's contents on Tuesday.
As well as Flower, Pietersen also criticised a group of senior England bowlers, including now retired off-spinner Graeme Swann, and currently injured wicketkeeper Matt Prior, whom he accused of creating a "bullying" culture by demanding some fielders apologise on the field for dropped catches but not asking the same of their friends in the side.
