Hi

I need to set some of our boxes to send mail through our smarthost. In 
the sendmail.mc file i have set the smarthost and rebuilt the 
sendmail.cf file. When i send a mail locally on the box though i get 
this error

Diagnostic-Code: SMTP; 553 5.1.8 <root at localhost.localdomain>... Domain 
of sender address root at localhost.localdomain does not exist

What else do i need to edit as there is something that talks about 
sending from unresolvable domains but this is already allowed i think


FEATURE(`accept_unresolvable_domains')dnl

any ideas ?

thanks
