I'm running sendmail 8.6.11, the Linux 1.2.1 kernel, and Linux libc 4.5.26.
When I try to send mail to a host that doesn't exist in my domain, e.g.,
"nohost", sendmail reports "Deferred: Name server: nohost: host name lookup
failure" for three days instead of immediately bouncing the message with "Host
uknown". I believe that this problem is new with either a recent version of
sendmail or a recent Linux kernel.
My /etc/host.conf says: "order hosts, bind" and "multi on".
Does anybody have any suggestions about what may be causing this or how to fix
