in a shell it works fine

but i talk about cronjobs like "8,38 * * * * root 
/usr/local/bin/spamfilter-fetch-samples" where the shell-script invokes 
systemd-run which finally calls a php-script producing output if there 
where sammples on the imap-folders not already classified with BAYES_99

the intention is to use systemd-capabilities like "-p 
ProtectSystem=full,ProtectHome=yes" starting with F24 and behave like a 
classical cronjob -> producing emails to all administrators
