[Dovecot] Antispam plugin problem (CRM114)

[Davide]

Hi to all, sorry in advance for my poor english, this is the first time 
that i wrote to a list if i make mistake .... excuseme.
My problem is this: i have dovecot 2.1.8 installed and functioning from 
2 years one week ago i have installed crm114 for my last spam detection 
filter "version 20100106-BlameMichelson (TRE 0.8.0 (BSD))"
My mail system is qmail that through .qmail default correctly tag with 
X-CRM114-Version: 20100106-BlameMichelson ( TRE 0.8.0 (BSD) ) MR-27CA1CFB
X-CRM114-CacheID: sfid-20120927_105129_798028_B0035817
X-CRM114-Status: GOOD (  28.64  ) headers

dovecot.conf is as follow:

plugin {
   . . .
   antispam_signature = X-CRM114-CacheID
   antispam_verbose_debug = 1
   antispam_debug_target = stderr
   antispam_backend = crm114
   antispam_signature_missing = error
   antispam_trash = Trash
   antispam_spam = SPAM
   antispam_unsure = UNSURE
   antispam_crm_binary = /opt/crm114/mailreaver.crm
   antispam_crm_args = --fileprefix=/opt/crm114/
   . . .
}

protocol imap {
   . . .
   mail_plugin_dir = /usr/local/lib/dovecot
   mail_plugins = $mail_plugins quota imap_quota mail_log antispam
   . . .
}

I have a sieve default compiled script that automatically put mails in 
SPAM folder or UNSURE folder if respectively in message hedere there is 
the evaluation of crm114 (UNSURE or SPAM).

When i move mails incorrectly tagged by crm (for example from SPAM to my 
inbox or from UNSURE to SPAM) thunderbird (company official mail client 
ver 15.01) go in error with the following message:

"Operation failed over folder 'UNSURE'. Server for account 
davide.marchi at mail.cgilfe.it said: [CANNOT] Failed to call crm114 binary.."

I dont'know where is my mistake if someone can help me is much 
appreciated Thank you
