And the Sieve script:
------- start sieve script --------- require ["vnd.dovecot.execute", "fileinto", "mailbox", "vnd.dovecot.debug"];
debug_log "about to execute"; if not execute :pipe "foofilter" { debug_log "if condition fulfilled"; fileinto :create "test-spam"; debug_log "about to stop"; stop; } debug_log "after execute"; ------- end sieve script ---------
The user's sieve log looks like:
sieve: info: started log at Nov 13 16:56:32. test-foofilter: line 3: info: DEBUG: about to execute. test-foofilter: line 4: error: execute action: failed to execute to program `foofilter': refer to server log for more information. [2018-11-13 16:59:57]. test-foofilter: line 5: info: DEBUG: if condition fulfilled. test-foofilter: line 7: info: DEBUG: about to stop. info: msgid=20181113155632.k6pybm45sdwwp2bs@blitz.conuropsis.org: stored mail into mailbox 'test-spam'.

Hi,
Running dovecot 2.2.27 (c0f36b0) on Debian GNU/Linux stable (version 9.6), I'm trying to use the execute command in a sieve script, with direct execution (not service socket).
The script is executed, and returns (the process exits), but the dovecot-lda process seems to not notice, and thinks the script did not terminate. After sieve_execute_exec_timeout has passed, it sends a TERM, a bit later a KILL and then logs a failure.
The "ps -Af f" looks like: S 0:00 \_ /usr/sbin/exim4 -Mc 1gMazS-0007IV-RB S 0:00 \_ /usr/lib/dovecot/dovecot-lda -f master@blitz.conuropsis.org Z 0:00 | \_ [foofilter] <defunct> S 0:00 \_ /usr/sbin/exim4 -Mc 1gMazS-0007IV-RB
The dovecot debug log looks like:

The script is very simple:
#! /bin/sh
cat > /dev/null exit 1
Anyone has a clue? Thanks in advance.
