I remember, that I also struggled for quite a while until I figured it
out. Here is what I used on my FreeBSD Dovecot installation ...
Remember, that the following code is working on "dovecot --version
1.2.12" ... but it could also be valid for later versions. I simply
havn't checked it out yet.
### Dovecot AntiSpam ###
# mail signature (used with any backend requiring a signature)
#antispam_signature = X-Spam-Status
#antispam_signature_missing = move
antispam_mail_sendmail = /usr/local/etc/dovecot/sa-learn-helper.sh
antispam_mail_sendmail_args = --username=%Lu
antispam_mail_spam = --spam
antispam_mail_notspam = --ham
antispam_mail_tmpdir = /tmp
antispam_spam = Spam
#antispam_unsure = Virus
antispam_trash = Trash
echo '#!/usr/local/bin/bash

/var/log/DoveDamnAntiSpam.log
/usr/local/bin/sa-learn "${1}" "${2}" "${3}" "${4}"
exit 0

chmod 0777 /usr/local/etc/dovecot/sa-learn-helper.sh ;

Hi there,
I've already asked this question on FreeBSD forums without getting any
response. So, I thought it's a good idea to ask it again here.
I've setup Dovecote2 (2.2.13) + Postfix + SpamAssassin on my FreeBSD 10
VPS and it works flawlessly. Though, I couldn't setup the Dovecot
Antispam plugin to train SpamAssassin when I move mails to the Junk
folder.
I installed the plugin from FreeBSD ports and followed the official
documentation [1] and the man page [2] without any success.
This is my configuration:

And, this is the script /mail/sa-learn-pipe.sh:

rm -f /tmp/sendmail-msg-$$.txt
echo "$$-end" >> /tmp/sa-learn-pipe.log
exit 0
########
I made it excecutable by all users using chmod a+x
/mail/sa-learn-pipe.sh
The problem is, there is no log in /var/log/maillog regarding the
Antispam plugin, and the script won't get called when I move any message
in/out to/from Junk folder.
I'll appreciate any help.
