The receiving machine performed a reverse DNS lookup and it came back with
different information.   If your server is truly setup right and you aren't
hijacking someone else's domain name, you should check your DNS setup and
verify that the reverse DNS configuration is correct.

Does anybody know what the following smtp error message means and how do I
fix it.

#5.5.0 smtp;553 sorry, envelope sender must have a valid 
domain name (#5.7.1)

Many thanks
