So far I've had no luck getting the bash script to call _any_ external programs. I can't even write a file to /tmp/, so it's not a filesystem permissions issue. The sieve script has no issues finding and executing the bash script, it just does nothing other than return an exit code.

Can you provide doveconf -n and your sieve rules? And the script?

Also if you're on systemd, you will likely have PrivateTmp=yes in the unit, so /tmp becomes /tmp/*systemd*dovecot*/tmp
