Error 553 : Malformed address

[Langevin, Rene]

Hi,

        I have Ex5.5 Sp4 running on NT4 Sp6a.  All my users run Outlook
2000, but I have 5 users with Mac using Eudora 5.1.  One of them has an
e-mail at home looking like that :

        [EMAIL PROTECTED]

        When I send a test e-mail, I don't have any problem, but when he
send a test, Eudora report the error 553 : Malformed address

Has anyone encounter this problem before?
