Now that we have a running named(8) name server, and a version of sendmail(8) capable of querying it, I'd like to make use of it. I hear a lot about MX records, but as yet I have not figured out exactly what they are nor how to use them. The BIND documentation mentions their existence and how to specify them in the named cache files, but it does not explain how they would be used. The sendmail documentation I have doesn't mention them at all. So, can someone answer these questions for me (and I doubt if I'm the only one that wants to ask): 1) What exactly is the purpose of an MX record? 2) How do I go about using one at this site to make delivery to our domain more reliable? 3) How do I use the MX records provided by other sites? Thanks for any enlightenment anyone provides. --Greg -- UUCP: {hplabs, seismo, nbires, noao}!hao!woods CSNET: woods@ncar.csnet ARPA: woods%ncar@CSNET-RELAY.ARPA INTERNET: woods@hao.ucar.edu
