When I post a msg, my name are converted to this: "=?ISO-8859-1?Q?Feij=F3?=

How can I prevent that ??? Outlook post correct, with 5 letters only

My code are:

        idMsg := TIdMessage.Create(Self);
        idmsg.Subject := edSubj.Text;
        idmsg.From.Name := User.Name;
        idmsg.From.Address := User.Email;

This is causing problems with other system, hows I have no control :(
