Trying to replace anti spam plugin with IMAPSieve; no joy
I?m trying to follow the instructions on the wiki to move from antispam to
IMAPSieve, but it?s not working at all. A bit of a background:
dovecot-core 2:2.3.8-4~buster
dovecot-imapd 2:2.3.8-4~buster
dovecot-lmtpd 2:2.3.8-4~buster
dovecot-managesieved 2:2.3.8-4~buster
dovecot-pgsql 2:2.3.8-4~buster
dovecot-pop3d 2:2.3.8-4~buster
dovecot-sieve 2:2.3.8-4~buster
dovecot-solr 2:2.3.8-4~buster
My regular sieve scripts work fine for messages arriving through LMTP. I?ve
updated my 20-imap.conf thusly:
##
## IMAP specific settings
##
protocol imap {
mail_max_userip_connections = 30
# Space separated list of plugins to load (default is global mail_plugins).
mail_plugins = $mail_plugins imap_acl imap_sieve
}
plugin {
sieve_plugins = sieve_imapsieve sieve_extprograms
sieve_trace_dir = /tmp
sieve_trace_level = matching
# From elsewhere to Spam folder
imapsieve_mailbox1_name = Spam
imapsieve_mailbox1_causes = COPY
imapsieve_mailbox1_before = file:/usr/lib/dovecot/sieve/report-spam.sieve
# From Spam folder to elsewhere
imapsieve_mailbox2_name = *
imapsieve_mailbox2_from = Spam
imapsieve_mailbox2_causes = COPY
imapsieve_mailbox2_before = file:/usr/lib/dovecot/sieve/report-ham.sieve
sieve_pipe_bin_dir = /usr/lib/dovecot/sieve
sieve_global_extensions = +vnd.dovecot.pipe +vnd.dovecot.environment
}
=======
I created the report-spam.sieve and report-ham.sieve scripts in
/usr/lib/dovecot/sieve and compiled them with sievec:
require ["vnd.dovecot.pipe", "copy", "imapsieve",
"environment", "variables"];
if environment :matches "imap.mailbox" "*" {
set "mailbox" "${1}";
}
if string "${mailbox}" "Trash" {
stop;
}
pipe :copy "sa-learn-pipe.sh" [ "ham" ];
=======
require ["vnd.dovecot.pipe", "copy", "imapsieve",
"environment", "variables"];
pipe :copy "sa-learn-pipe.sh" [ "spam" ];
=======
Lastly, I have the sa-learn-pipe.sh script in /usr/lib/dovecot/sieve:
#!/bin/bash
echo "`date` learning $*" >> /tmp/sa-learn
# We run amavisd-new on another Kubernetes pod and communicate with it via socat
on both ends; this worked with the old antispam plugin.
if [ "$*" = "ham" ] ; then
socat - TCP:amavis:4443
else
socat - TCP:amavis:4444
fi
exit 0
=======
The /usr/lib/dovecot/sieve directory looks like this:
drwxr-xr-x 1 root root 4096 Nov 4 20:49 .
drwxr-xr-x 1 root root 4096 Nov 3 20:06 ..
-rwxr-xr-x 1 root root 237 Nov 3 15:56 report-ham.sieve
-rw-r--r-- 1 root root 384 Nov 4 20:49 report-ham.svbin
-rwxr-xr-x 1 root root 122 Nov 3 15:56 report-spam.sieve
-rw-r--r-- 1 root root 290 Nov 4 20:49 report-spam.svbin
-rwxr-xr-x 1 root root 208 Nov 3 17:58 sa-learn-pipe.sh
When the sieve scripts run when mail arrives during LMTP delivery they dutifully
log their work in /tmp, so I know sieve works and sieve logging works too. The
sieve scripts above never log anything, nor does /tmp/sa-learn ever get created
as it would if sa-learn-pipe.sh were ever run. As far as I can tell I?ve
duplicated the configuration from the wiki almost exactly, but dovecot is just
not running the sieve scripts when messages are moved into/out of Junk.
What am I missing?

It does not affect LMTP delivery. Try enabling 'mail_debug=yes' to see why it does not work. Aki
