- Yet another IDA-sendmail set up question. On a network of Suns, I want
- a main mailhost and client machines. Currently I run NIS on the
- network for host lookups. The NIS server maps were made with the -b
- option so that name lookups that fail at the local NIS level will then
- be handed to DNS. The NIS master server has a /etc/resolv.conf file
- that points to the DNS machine (not under my control). The result
- works, from any client I can ping/telnet/etc. a host; if "local" then
- it works (via NIS), if not local it still works (via NIS handing off to
- DNS). I like this hand off scheme because my access to the name server
- is not perfectly reliable and this way my hosts can communicate among
- themselves even when the DNS machine is down.
-
- So now I compile IDA-sendmail with DNS/BIND stuff built in. The client
- I test on does not have a resolv.conf file and thus name lookups won't
- work. Should I take the DNS stuff out (thus allowing name lookups
- using NIS)? If I do this will I lose the ability to deliver to MX
- records (which I am required to do)? How can I get the best of both
- worlds?
-
- Thanks for any pointers,
- Robert
