probably i fail to see something important here, but to me 'pipe' seems 
correct.

This is really a nifty idea, i'll give it a try and report back on that.

Er, this module is called "mailtrain", isn't it? At least in antispam 
changeset 50:0319240072d8. You should get an error "configured 
non-existent antispam backend: pipe"



 antispam_mail_notspam = h...@example.org
 antispam_mail_sendmail = /usr/sbin/sendmail


You could replace this program by a shell script to get the info, that it 
is called, e.g.:


 /usr/local/bin/mailtrain.sh
#!/bin/bash

( date
  id -a
  echo "$@"
  /usr/sbin/sendmail "%@"
  rc=$?
  echo rc=$rc
  exit $rc
) >>/tmp/mailtrain.log 2>&1
=

So you see, if the program is fired up and which uid is used and what 
problem sendmail had.


Kind regards,

filesystem is ext4
antispam util is dspam

I'm trying to utilize the imap plugin antispam for retraining spam/ham when 
moving mail from/to spam folders.

antispam plugin is loaded and imap service itself runs correctly
logfile excerp for login:

When I move mail into or out of imap folders named Junk or SPAM I would 
expect, that the antispam plugin kicks in and pipes the mail to dspam. 
Apparently this does not happen, nothing gets piped, though the mail is still 
moved to the folder.

I've already tried dspam-exec as a backend as well, but that fails even ealier 
right after imap login with:
Jan 16 19:26:15 mailhost dovecot: master: Dovecot v2.1.7 starting up (core 
dumps disabled)

Jan 16 19:26:45 mailhost dovecot: imap(user): Fatal: master: service(imap): 
child 4701 returned error 3

settings were:
antispam_backend = dspam-exec
antispam_dspam_binary = /usr/bin/dspam
antispam_dspam_args = --client;--source=error;--user;%u;--signature=%%s


I've also tried with:
antispam_backend = dspam-exec
antispam_dspam_binary = /usr/bin/dspam
antispam_dspam_args = --source=error;--user;%u

those settings actually do not produce the problem after the imap login, but 
they still do not react to moving mail into/from spam folders. 

I've also tried to utilize
   antispam_spam = Junk
or
   antispam_spam_pattern = SPAM
instead of
   antispam_spam_pattern_ignorecase = SPAM;Junk
but neither makes a difference.

Thx in advance for any advice.

kind regards,
Michael Moerz
