         Re:      Registration Statement on Form S-3

Ladies and Gentlemen:

         We have acted on behalf of PopMail.com, inc. (the "Company") in
connection with Amendment No. 2 to a Registration Statement on Form S-3 (the
"Registration Statement") to be filed by the Company with the Securities and
Exchange Commission on April 4, 2000 relating to the registration under the
Securities Act of 1933, as amended, of a maximum of 2,435,001 shares of common
stock, par value $.01 per share (the "Common Stock"), issuable by the Company as
follows: (a) 2,160,001 upon conversion of the 4% Convertible Debentures and
payment of interest thereunder; and (b) 275,000 shares issued in connection with
the exercise of certain warrants to purchase shares of the Company's Common
Stock.

         Upon examination of such corporate documents and records as we have
deemed necessary or advisable for the purposes hereof and including and in
reliance upon certain certificates by the Company, it is our opinion that:

         1.       The Company is a validly existing corporation in good standing
                  under the laws of the State of Minnesota.

         2.       The Common Stock has been duly authorized and, when issued as
                  described in the registration statement, will be legally
                  issued, fully paid and non-assessable.

         We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement.

                                Very truly yours,


                                Maslon Edelman Borman & Brand, LLP
