Great, thanks a lot. I just tried it this way and it works. Thanks a lot!

There is one thing I dont understand even after reading it several
times: If deliveries are made with the rights of the receiving user
(=nagios), why do I get this error:
postfix/local: to=<nagios at nagiosalert.xxx.net>, relay=local,
delay=3, status=bounced (Command died with status 1:
output: local: fatal: execvp
The line in /etc/aliases is:
this points to:
-rwxrwxr-- 1 nagios admin handle-RAID-mail
-rwxrwxr-- 1 nagios admin submit_check_result
which outputs to:
prw-rw---- 1 nagios nagcmd nagios.cmd
In my understanding it should have been delivered, w/o making an extra
aliases-file, since the receiving user has rw(x) on all files in the
chain. My misunderstanding or wrong documentation?
Anyway, the concrete problem has been solved, thanks again - also to
Daniel and Paul for there really interesting suggestions - regards, Ingo.
