This mentions the St. Petersburg postmark:

Thank you.

FBI officials said the letter, from an anonymous writer, had a postmark from St. Petersburg, Fla. There are "some similarities" between the handwriting in the NBC letter and a suspicious letter received at the New York Times, which also was mailed from St. Petersburg, according to Mawn. Tests on the powder in the NBC letter proved negative, Lack said, but on Friday a skin biopsy came back positive. That prompted NBC to immediately cordon off its third-floor offices in Rockefeller Center so federal investigators could examine the newsroom site for contamination.

Thanks for the link. This verifies Nogbad's ealier post.

Did I read that article wrong? What I understood from it is that this was the hoax letter to the NY Times--which, although containing a mysterious powder, was found not to be anthrax. Someone please correct me if I'm wrong on this one.
