Can someone tell me how sendmail decides how to send mail?
 
we have a mailertable with entries for domains pointing to example:
 
abc.com                      esmtp[x.x.x.x]
 
Should this be used to decide where to send the mail?
 
We think our system is using DNS to decide how to route the mail out.  We
don't want to use DNS for one domain.
 
Does the resolv.conf file hold the entries for DNS used by the server OS
or for SendMail?
Is there another file used for DNS configuration of SendMail?
 
Can anyone help?
 
many thanks
