Organization: EDMBBS Marketing Date: Tue, 05 Mar 96 05:02:55 EST Sender: owner-isp@freebsd.org Precedence: bulk This is not a FreeBSD-specific question, but other than that I think I have the right mailing list... I'm trying to configure DNS for our site, which will soon be connected to the internet. I have named.hosts set up so that access to edmnet.com connects to kirk.edmnet.com. I've set this up as shown in RFC-1912, with the two 'A' records pointing to the same IP address. I also have kirk.edmnet.com set up as primary MX for the domain. The problem is, when I try to send mail to user@edmnet.com, sendmail complains that "MX record for edmnet.com. points back to kirk.edmnet.com" and the mail bounces. I don't know if this is a problem with DNS or sendmail. I can't see anything wrong with the named.hosts file, and the sendmail.cf file is the default that comes with FreeBSD. RFC-1912 mentions a "Cw" flag for sendmail, but I can't find enough documentation on this option to determine exactly what it does, and if/how it can fix the problem. This is a fairly basic setup, but I can't find any info on this problem... I'd appreciate any help I can get.
