[Dshield] modify hosts in a internet email server

When some server or firewalls without a internet domain send emails to 
our mail server, it rejects because the domain doesn't exists.
So I changed the hosts to add a line for the domain like:
500.200.3.1 unkwon-domain
How my server never should send emails to this machines, don't need a 
real ip.
You think it should be a problem from the point of view of security or 
spam?
Thanks
