We have reviewed the parties' briefs and the record on appeal. We affirm the judgment of the tax court essentially for the reasons stated in the order of dismissal for lack of jurisdiction, dated March 8, 1993. We add only that our colleagues in the Seventh and Eleventh Circuits have rejected the same argument proffered by appellant and have concluded that "[i]t is apparent from the numerous references to 'United States mail' in the statute and regulations that section 7502 is intended to apply only to mail delivered by the United States Postal Service and not also to items delivered by a private delivery service." Pugsley v. Commissioner, 749 F.2d 691, 693 (11th Cir. 1985) (footnote omitted), quoted in Petrulis v. Commissioner, 938 F.2d 78, 79-80 (7th Cir. 1991).
