I am trying to add a signature to all messages and it should be possible via vnd.dovecot.filter, the problem is that any script I try to filter through just hangs. I am running on FreeBSD 11.2 and I tried with dovecot 2.2.32 & pigeonhole 0.4.19 and with dovecot 2.3.2 && pigeonhole 0.5.2. In both cases, the output from dovecot is the same:

Feb 19 18:24:22 mx13 dovecot: lda(user1): Debug: sieve: action filter: running program: append Feb 19 18:24:22 mx13 dovecot: lda(user1): Debug: Mailbox stdin: Opened mail UID=1 because: mail stream Feb 19 18:24:22 mx13 dovecot: lda(user1): Debug: waiting for program /usr/local/gtech/sieve/append' to finish after 3 msecs Feb 19 18:25:22 mx13 dovecot: lda(user1): Debug: program /usr/local/gtech/sieve/append'(55055) execution timed out after 60000 milliseconds: sending TERM signal Feb 19 18:25:27 mx13 dovecot: lda(user1): Debug: program `/usr/local/gtech/sieve/append' (55055) did not die after 5000 milliseconds: sending KILL signal

at first I tried using my actual script but since it was failing I switched to a simple shell script:

#!/bin/sh

cat /dev/null

echo "hey"

exit 0

I got that idea after reading: http://dovecot.2317879.n4.nabble.com/execute-sieve-command-fails-to-notice-s...

The result is unfortunately the same. From what I can gather ( ran it inside strace/truss too), dovecot-lda hangs on the output.

Is this accurate ? How can I get this to work ?

Hi!

This problem has been fixed in 2.3.4.
