Unless we agree that it's off the record it's on the record say

ADAM NAGOURNEY and MARC SANTORA of the New York Times

For all the anticipation that preceded Mr. Thompson’s appearance, his new rivals barely mentioned him, reflecting in part a sense within the party that his first weeks as an official candidate had not gone well. (Mr. Giuliani’s campaign, however, did dispatch an unsolicited “not for attribution” e-mail to reporters arguing that Mr. Thompson had, as a member of the Senate in 2001, been part of a coalition that sought to decrease the size of tax cuts proposed by Mr. Bush).

It seems that the Giuliani campaign had reason to believe that it could unilaterally declare something to be "not for attribution". About time journalists decided to stop putting up with that.

Also the first thing I've heard about Thompson that I like.
