The sendmail log is   /var/log/maillog

Your box does NOT need to be running it's own DNS server, just make
sure it can resolve the names of computes you are sending mail to and 
itself.  Either point it to a good DNS server in /etc/resolv.conf or 
enter the IP's and host names in /etc/hosts .   Then check to make 
sure it works by looking up the hostnames with the command "nslookup".
