Hi all,

I'm trying to do the same thing everyone else is: having rspamd learn_ham or learn_spam depending on where I move a message. My current problem is that Dovecot seems to be reporting success, but nothing ever happens -- the script somehow fails to run.

I'm currently using a dummy script that just writes a file to /tmp, until I can get this much working, at least. My bin_dir:

me@server:/usr/lib/dovecot/sieve# ls -l total 40 drwxr-xr-x 2 root root 4096 Jan 21 03:35 ./ drwxr-xr-x 4 root root 12288 Aug 29 06:28 ../ -rw-r--r-- 1 root root 112 Jan 21 02:17 report-ham.sieve -rw-r--r-- 1 root root 250 Jan 21 02:17 report-ham.svbin -rw-r--r-- 1 root root 112 Jun 3 2019 report-spam.sieve -rw-r--r-- 1 root root 258 Jun 3 2019 report-spam.svbin -rwxr-xr-x 1 root root 105 Jan 21 03:35 rspamd_ham.sh* -rwxr-xr-x 1 root root 43 Jun 3 2019 rspamd_spam.sh*

Then the report-ham.sieve script:

require ["vnd.dovecot.pipe", "copy", "imapsieve", "fileinto"];

pipe :copy "rspamd_ham.sh";

#fileinto "INBOX";

And the dummy rspamd_ham.sh script:

#!/bin/bash

#exec /usr/bin/rspamc learn_ham

tim=date +%M-%S

echo "${1}" > "/tmp/${tim}_results.txt"

I can confirm the above script works correctly when run from the command line, both as root and the vmail user. When run as part of the sieve process, no errors are reported, but no file is created under /tmp. From the logs:

Near as I can tell, the first time this runs after a dovecot restart, I get this error instead:

Error: write(program stdin) failed: Broken pipe Error: sieve: pipe action: failed to program `rspamd_ham.sh': refer to server log for more information.

But that only happens once, then it behaves as above.

The "Opened mail UID=XXX" bit changes UID (increments monotonically?) every time.

I think that ought to be everything but my dovecot -n. Thanks in advance for any help.
