Hi,
I have installed dovecot-antispam and configured it this way (as in the doc)
with the dspam exe:
protocol imap {
mail_plugins = antispam
mail_plugin_dir = /usr/lib64/dovecot/imap
}
plugin {
# For dovecot-antispam:
antispam_signature = X-DSPAM-Signature
antispam_trash = trash;Trash;Deleted Items
antispam_spam = SPAM;Junk
#antispam_unsure = unsure
antispam_dspam_binary = /usr/bin/dspam
antispam_dspam_args = --deliver=;--user;%u
antispam_mail_tmpdir = /tmp
}
But it does not work and really I cannot figure it out for two days, because
I can find no log wherever, where it writes it does (or try to do)
something, nor in the dovecot logs, nor in the dspam logs. But I know
something is happening because when I try to move a spam from my inbox to
the Junk folder, it fails with an error telling it could not move the email.
At the opposite, when I deactivate the antispam plugin, I can move normally
the emails.
So what could I do to fix my issue or at least diagnose it (where would I
find logs of what is happening?)?
Thanks.
Jehan

The second should not appear for dovecot >=1.1.7 (thanks Timo! ;) I was getting [1] - don't know why this error shows, cause my log said, that dspam was already called with correct parameters I had to patch dovecot-antispam sources to make it work. Apply the following patch and compile dovecot-antispam again: --- dspam-exec.c.orig 2008-11-11 16:02:20.000000000 +0100 +++ dspam-exec.c 2008-11-11 16:02:30.000000000 +0100 @@ -178,13 +178,14 @@ int ret = 0; while (item) { - if (call_dspam(item->sig, item->wanted)) { + /* if (call_dspam(item->sig, item->wanted)) { ret = -1; mail_storage_set_error(ctx->box->storage, ME(NOTPOSSIBLE) "Failed to call dspam"); break; - } + } */ + call_dspam(item->sig, item->wanted); item = item->next; } It works for me now (dovecot-1.1.10, dovecot-antispam-1.1, FreeBSD Current) with this entries in dovecot.conf: antispam_dspam_binary = "/usr/local/bin/dspam" antispam_dspam_args = --source=error antispam_dspam_args = --user=%u Hope it helps.

I though I was replying to the whole ml. Apparently the ml is not very well configured because a reply does not reply to the whole ml, but to the single sender.

It was just telling me that it could not move the message. I configured a Thunderbird then and it displayed indeed this message 'Failed to call dspam'. So I made your trick, I compiled myself the dovecot-antispam library and now I can move messages... But are you sure that it is the right method and that the dspam training is indeed called? Because if I read well this piece of code, it looks like it was checking if the dspam training was successful. We commented out this check, so now maybe it fails and we copy the messages anyway to Junk/ even though no training really occurred. And when I check the logs or the dspam_stats, I don't see any change, even though I guess this retraining should be seen as a change in the stats, no?> > Antispam plugin is easy to understand: when you configure antispam_spam > = SPAM it will set SPAM folder as his special folder to observe.

By the way, when one has the item "X-DSPAM-Result: Innocent" in the header, it means the email is not a spam, does'nt it (right now I am focusing on having this plugin working for training purpose, but currently not much is working perfectly as expected in my email spam system)?> > You can provide some info from your log files, i'll try to help.

Hi all,
just to say that finally the patch of Marcin worked great. Just my
configuration is different from yours to get it work:
antispam_signature = X-DSPAM-Signature
antispam_trash = trash;Trash;Deleted Items
antispam_spam = SPAM;Junk
antispam_dspam_binary = /usr/bin/dspam
antispam_dspam_args = --client;--source=error;--user;%u
antispam_mail_tmpdir = /tmp
The difference here is in the syntax. You write "--user=somemail"
though in
the manual, it is written "--user somemail". But also you were
proposing 2
lines "antispam_dspam_args" though in all my tests, when I was doing
such a
thing, the second line seemed to override the first (in the launch logs,
only the second line was displayed, so I guess...).
Are you sure that it works exactly the way you intend to, Marcin? And that
the "--source=error" (your first line) is indeed added as a parameter
to the
call of dspam?
For the patch to the dovecot-antispam, probably it should not be integrated
"as is", but I guess that the return code of call_dspam function must
probably be checked and fixed if the call can succeed but still give a
failure return code. I set Johannes as a main recipient, maybe you will see
this email.
Bye and thanks all.
