Yes, thank you Daniel for pointing me to this subjects. Now I got a bit 
a deeper understanding how a file gets executed.
My problem is that I do not exactly know from the error message who is 
starting what by which effective group id and to what group id it tries 
to switch. All guessing did not lead to a result.

I tried: postfix is starting deliver with the effective group id 
"postfix" and wants to set the group id either to "mail" or to "rolf".
But no success.
