It seems that I found the problem. After searching in the sourcecode of 
dovecot-lda (smtpclient.c) I found that path to sendmail is hardcoded to 
/usr/lib/sendmail. In my system (www.linuxfromscratch.org) there was the 
path /usr/sbin/sendmail.So a symbolic link helped me ....
I think, it would be a good idea, to put such things in a configuration 
file. Did I miss something? Is there one? If yes, what are the 
configurable options?
Another good thing could be to simple test the existance of 
/usr/lib/sendmail and generate an errorlog entry, if it is missing.
