Hello,
I'm running into an issue with DSPAM and Dovecot with this setup :
- Ubuntu Server 14.04.1
- Dovecot 2.2.9 with dovecot-antispam
plugin {
antispam_allow_append_to_spam = YES
antispam_backend = dspam
antispam_debug_target = syslog
antispam_dspam_args =
--deliver;--user;%u;--source=error;--signature=%%s
antispam_dspam_binary = /usr/bin/dspam
antispam_dspam_result_header = X-DSPAM-Result
antispam_signature = X-DSPAM-Signature
antispam_signature_missing = error
antispam_skip_from_line = NO
antispam_spam = Spam
antispam_trash = Trash
sieve = ~/.dovecot.sieve
sieve_default = /etc/dovecot/sieve/global.sieve
sieve_dir = ~/sieve
sieve_global_dir = /etc/dovecot/sieve/
sieve_global_path = /etc/dovecot/sieve/global.sieve
}
- DSPAM 3.10.2

When I'm moving a spam from my Spam folder to another folder (or from
another folder to my Spam folder), I got this error :
Signature retrieval for '%s' failed. Unable to find a valid signature.
Aborting.
Here's the concerned email header :
X-DSPAM-Result: Spam
X-DSPAM-Processed: Mon Jan 5 15:05:07 2015
X-DSPAM-Confidence: 0.9982
X-DSPAM-Probability: 1.0000
X-DSPAM-Signature: 54aa9a1318642065924526
With debug mode enabled, i have more details :
input args: /usr/bin/dspam --source=error --class=innocent
--signature=54aa9a1318642065924526 --deliver --user XXXXXXX
--source=error --signature=%s
Running this command works fine (as root, i got nothing printed as dspam) :
$ dspam --user XXXXX --class=innocent --source=error
--signature=54aa9a1318642065924526 --stdout --deliver=summary
X-DSPAM-Result: XXXXXX; result="Innocent"; class="Innocent";
probability=0.0000; confidence=0.00; signature=54aa9a1318642065924526
I updated my dovecot antispam_dspam_args parameter to this, hoping to
remove the second signature parameter : --deliver;--user;%u
But it still the same issue.
Maybe this extra signature=%s comes from dovecot-antispam ?

Guillaume
