The payment is believed to have been transferred in 2008 from a FIFA account to the account of former senior FIFA executive Jack Warner, at the request of Secretary General Jerome Valcke.
"I have never received confirmation but more important I would like to know when the transfer can be done," Valcke said in the email from December 7, 2007.
In the email, Valcke went on to say that its content was based on discussions between FIFA and the South African government, as well as "between our President and H.E. President M’Beki."
A FIFA spokeswoman, however, said that the email did not prove either Blatter or Valcke's involvement, but only constituted information. She pointed out that the transaction was authorized by the then-chairman of the Finance Committee.
According to The Telegraph, the email refers to a September 2007 letter, in which Valcke detailed South Africa’s intention to pay $10 million to a program for African diaspora living in in the Caribbean.
The email has surfaced amid a corruption scandal surrounding the football governing body that gained momentum when, in late May, seven FIFA officials were arrested on corruption charges two days before its presidential elections.
On May 29, Blatter was reelected president but four days later announced his resignation from the post.
