antispam plugin pipe script seems not to be called when it "should be"
Hello,
(Full "doveconf -n" output is at the end of this message.)
I'm attempting to recreate a "recipe" I had used successfully for
quite
some time (in Ubuntu 12.04 LTS), which allowed me to train
SpamAssassin's Bayes database when someone dragged an email message from
one sub-folder of the account to another.
I later tried to re-implement it (in Ubuntu 14.04 LTS), and core-dumps
resulted. I posted to this list about it several times, but nobody was
ever able to help me solve the problem.
I just tried the same (in Ubuntu 16.04 LTS), hoping that the source had
evolved since then, and while I don't see a core-dump, the pipe script
doesn't seem to be called.
I've booby-trapped the pipe script with quite a bit of debugging output,
which should be written to a file, but I don't see any indication that
the pipe script is ever executed.
When logged-in as an IMAP user, and I drag a message from the user's
Inbox into the "Spam" folder, I do see the following activity in the
syslog:
Aug 18 22:12:15 example.com imap: antispam: mailbox_is_unsure(Junk): 0
Aug 18 22:12:15 example.com imap: antispam: mailbox_is_trash(INBOX): 0

Aug 18 22:12:15 example.com imap: antispam: running mailtrain backend

Aug 18 22:12:15 example.com imap: antispam: running mailtrain backend
program /bin/bash
Aug 18 22:12:15 example.com imap: antispam: running mailtrain backend
program parameter 1 /usr/local/bin/sa-learn-pipe.sh
Aug 18 22:12:15 example.com imap: antispam: running mailtrain backend
program parameter 2 --spam
But the piped message is never delivered to the target mailbox.
The mail log at /var/log/mail.log does not register any activity when I
move messages (and maybe that's expected).
Here are the contents of the /usr/local/bin/sa-learn-pipe.sh script:

The permissions and mode on the script seem appropriate:

Yet, if I do this using the above content for the script, the "gtube" message is delivered successfully: # su vmail $ /usr/local/bin/sa-learn-pipe-test.sh The message arrives in the Inbox, presumably because -m "Training.$mode" does not "resolve" to anything, and per the documentation, the delivery destination will default to the Inbox in such cases. What's wrong with my the custom pipe script to which I posted a link in my previous message, I wonder? Thanks again for any assistance, -Ben
