Forgot to followup on this in case it's useful to someone in the future. The error had nothing to do with DNS configuration. This turned out to be an issue with /etc/mail/local-host-names. While local-host-names did exist and listed all domains for which I wanted to accept mail, I had overlooked the fact that local-host-names is a sendmail database type file, and had not run "makemap -e hash /etc/mail/local-host-names </etc/mail/local-host-names" to create the .db file. If sendmail can't read local-host-names it looks at /etc/hosts and does a reverse DNS. Gary
