It works, there was just a mistake in my command line :

$ sudo -u vmail /usr/bin/dspam --source=error --class=spam --signature=89,52900600118151560172939 --client --user [email protected]

     Hello again,

I'm running Gentoo AMD64 2013 with postfix, mysql, dovecot and dspam :
dovecot 2.2.8 (it was working fine with 2.2.6 after doing a chmod 4511
on dspam binary), dspam 3.10.2-r1 and dovecot-antispam-2.0_pre20130429
(recompiled after each dovecot upgrade).

I've set dspam to debug, and mail_debug to yes.

uid 1001 is user vmail (dovecot is running under vmail)
gid 12 is group mail (vmail is a member, with
mail,postfix,dspam,dovecot,apache)
All the necessary users are trusted in dspam configuration.

Here's my plugin settings :
antispam_verbose_debug = 1
antispam_debug_target = syslog
antispam_backend = dspam
antispam_allow_append_to_spam = NO
antispam_skip_from_line = NO
antispam_spam = Spam
antispam_trash = Trash
antispam_signature = X-DSPAM-Signature
antispam_signature_missing = error
antispam_dspam_binary = /usr/bin/dspam
antispam_dspam_args = --user;%u;--deliver=;--source=error;--signature=%%s
Configured to use the mail recipient

antispam_dspam_spam = --class=spam
antispam_dspam_notspam = --class=innocent
antispam_dspam_result_header = X-DSPAM-Result

When i'm moving an email to the dspam folder, Thunderbird throw me an
error : Failed to call dspam (email is dropped in the Spam folder
anyway, but a copy stay on my INBOX)

If i try to call dspam like this, it works :
sudo -u vmail /usr/bin/dspam --source=error --class=spam
--signature=4be87a9f953248352114216 --client --user vmail
Called spam using some other user.

Any idea ?

The user ghilt@... is not recognized in your dspam setup. You should
change the antispam config to use a static username, or make dspam
accept your recipient addresses.
