Wietse, is this what's expected?
AFAICT you are lacking write permission for the user.
This program must NOT be writable by users.
On my Fedora system the file is owned by root.
grep postdrop /etc/postfix/postfix-files
$command_directory/postdrop:f:root:$setgid_group:2755:u
I just downloaded the postfix package for Ubuntu 20.04 and it's the same.
