Ok. that makes sense, I guess.

It certainly should be possible to configure sendmail to consider
/etc/hosts before attempting a DNS lookup.
What does the 'hosts' entry in your /etc/nsswitch.conf look like?
To have name lookups check /etc/hosts before dns it should look like:
# /etc/nsswitch.conf
hosts: files dns
You do have the hosts specified in /etc/hosts with their fully qualifed
domain name don't you? and you do have ampr.org in your /etc/resolv.conf
'search' list I presume? e.g.
# /etc/resolv.conf
search ampr.org your.domain
