and you enclosed your .mc file.
I have everything that you have in your .mc file, including a service switch
file specially for sendmail and it still insists on carrying out lookups,
reporting that the network is unreachable naturally. As you may have guessed
from my earlier question about module net-pf-17 and what should I alias to it,
I have not been able to get diald to run so the delay while sendmail failed to
do a hostname lookup was not a problem, although very annoying.
The m4 routines in the RH packages do not support the nodns option at sendmail
v8.9.1 and the sendmail faq section 3.22 suggests that one remove dns from the
service.switch file and forward to a smart host. I notice that you, Pieter,
are using sendmail v8.8.something with the anti spam hacks. This makes me
wonder if the service switch option is broken in 8.9.1, in which case the
nodns setup will never work.
This would imply that diald will always come up to do a dns lookup using
sendmail v8.9.1.
I will try to find out if this issue has been raised in the sendmail archives.
(Note if you alter the Linux default switch file /etc/nsswitch.conf and are
running your own caching nameserver, you don't get any name lookups for
anything)
