sendmail with SMTP, but without DNS

Symptom:

You have configured a local net without Domain-Name-Services (DNS), all hostnames are defined in /etc/hosts, the hosts can be accessed via that name.

You can receive mails, however it is impossible to send mails. You see a message like

sendmail: Hostname lookup failed
in the file /var/log/messages.

Cause:

Sendmail was configured for SMTP and DNS. The entries in /etc/hosts aren't recognized at all.

Solution:

Further information concerning /etc/service.switch can be found in the file /usr/doc/packages/sendmail/op.ps, page 48f .
