What's wrong with 5.1.2 and 5.1.8 ?

     X.1.2   Bad destination system address

        The destination system specified in the address does not exist
        or is incapable of accepting mail.  For Internet mail names,
        this means the address portion to the right of the "@" is
        invalid for mail.  This code is only useful for permanent
        failures.

     X.1.8   Bad sender's system address

        The sender's system specified in the address does not exist or
        is incapable of accepting return mail.  For domain names, this
        means the address portion to the right of the "@" is invalid
        for mail.

Those look right to me.  Will adjust accordingly.
