Microsoft and the New York State attorney general have teamed up to fight spam.
At a conference next week, Microsoft and New York State attorney general Eliot Spitzer will receal details of legal action to be taken against spammers.
"This announcement is about a collaborative effort regarding spam," said Microsoft spokesman Sean Sundwall. He declined to give further details of the pact with the New York State attorney general.
Earlier this week US president George W Bush signed a bill into law establishing federal rules for commercial e-mail and penalties for unsolicited mass mailing.
In June, Microsoft said it had filed several lawsuits, 13 in the US and two in the UK, against spammers.
