Hi Doug,
    I guess you are using NIS based on the map question.  To make
sendmail work under Suse without dns, we had to add the following file
to /etc/mail:

# cat service.switch
# /etc/mail/service-nodns.switch
#
# Author: Werner Fink <feedback@suse.de>
#
# The only difference between /etc/nsswitch.conf and
# this file: There is NO colon after the service.
# Remark: this setup should avoid dialups.
#
# This file is required for HACK(nodns) or SENDMAIL_NODNS.
#
hosts           files
aliases         files

Hopefully that works for you.  Good luck.

David

I am seetting up a new system and moving services to it. It is functioning fine except for the following issue.

I moved all DNS to system 2 and set resolve.conf on system 1 to point to
the IP of system 2. nslookup on system 1 now does lookups fine using the
default system 2 DNS.

Ok now I stop bind on system 1. nslookup still work fine. BUT mail stops
(which is still on system 1) because it cannot reslove domains.

Does sendmail use a different map to dns than resolve.conf???
