Internal Mail

Hello Everyone,

   I have tmda working fine on my mail hub, but as a new user of this 
software I have some questions:

I have internal machine generated emails from batch processes that send 
mail to internal people.   However, TMDA blocks those now.  So I put the 
machines domain name in the filter file with a rule for "ok".  This works.

But, in general, how does one deal with the fact that locally delivered 
mail is challenged?   Is there a better way to do this?  (i.e. make an 
exception to your domain without putting it in the TMDA filter files and 
allowing spammers with your domain to send mail.)
