Re: [Dovecot] Dovecot antispam plugin bug: got an empty message
It looks that I have misconfigured the dovecot plugin:
plugin {
antispam_dspam_binary = /usr/bin/dspam # should be dspam
# antispam_dspam_binary = /usr/bin/dspamc # does not work
antispam_signature = X-DSPAM-Signature
antispam_signature_missing = move
antispam_spam_pattern_ignorecase = Junk;Junk.*
antispam_trash_pattern_ignorecase = Trash;Deleted Items
antispam_backend = dspam
antispam_dspam_args = --user;%u;--deliver=;--source=error;--
signature=%%s
antispam_dspam_spam = --class=spam
antispam_dspam_notspam = --class=innocent
}

It is few months ago I requested help with combination dovecot - dovecot-
antispam plugin and dspam.
Now I got into troubles with a lot of spam delivering to users inbox.
Problem described bellow is now better hidden but stil remains:
When moving a message from INBOX to Junk, dspam got an empty message.
I made a wrapper about dspamc and there is no input on stdio. The dspam was
not trained (got an empty message).
Looking to source code of dspam and antispam plugin I suspect the dovecot
not to sending any content to plugin when moving from inbox to junk.

Gentoo has included the antispam plugin from Johannes historically, but
added the fork by Eugene to support upgrades to dovecot 2.0. It is not
really made clear by the gentoo ebuild is that the forked plugin needs a
slightly different config.
I use the config below with dovecot 2.0.17 and a git checkout for
dovecot-antispam:

Thank you,
I have reconfigured my dovecot on gentoo and it looks now that it worked
properly.

[Dovecot] Dovecot antispam plugint got an empty message
Few weeks ago I upgraded dovecot from 1.2 to 2.0.16 and antispam plugin to
2.0_pre20101222. Since the upgrade I'm not able to move messages to my Junk
folder. In the maillog I have found this message:
dspam[25060]: empty message (no data received)
Message is copied from my INBOX to Junk folder, but dspam got an empty message
and sent an error return code. So the moving operation is not successfull and
the original message in INBOX was not deleted. The dspam was not trained (got
an empty message).
Looking to source code of dspam and antispam plugin I suspect the dovecot not
to sending any content to plugin.
Can you help me, please?
