After my Summary I got additional answers from

Hichem Boukottaya
Andrew Kyle
Steve Sandau
Mike Brodbelt
Lupe Christoph

With these information I was able to change the sendmail configuration 
so that it works now without compiling our own sendmail.

I finally used the following solution:

2. Modify submit.cf and sendmail.cf not to perform lookups and send 
straight to the mailhost:


R$* $| $* < @ $* > $* $: $2 < @ $[ $3 $] > $4

R$* $| $* $: $2


R$* $| $* < @ $* > $* $: $2 < @ $3 > $4

R$* $| $* $: $2

Thanks to all that answered.



My Original question was:

>We're trying to configure sendmail on a machine running Solaris 9 for 
>sending mails via an "smart"  relay host (DS... in /etc/mail/sendmail.cf)
>The problem we have is,  that sendmail trys to resolve the domain names 
>of the target email addresses, e.g. if we send an email to 
>bs@mysubdomain.mydomain.de sendmail trys to "resolve" 
>mysubdomain.mydomain.de . This fails because the nameserver used does 
>not know this domain and because of this sendmail does not send the 
>email to the relay.
>At least that is what the mail  people in our company told us. They also 
>told us  that the "normal" sendmail  daemon uses a file called 
>/etc/mail/service.switch to configure the name resolution but that the 
>use of this file is disabled in the sendmail daemon from Solaris 9.
>If we change the hosts entry in /etc/nsswitch.conf to "hosts: files" 
>instead of "hosts: files dns" everything works. 
>How can we tell sendmail to change this behaviour (because we must have 
>dns configured in /etc/nsswitch.conf)?
>Note that the connection to the mail relay and the DNS server are ok.
