[Dovecot] Another dovecot-antispam plugin can't call dspam

[Rob Klingsten]

Hi folks -

I am configuring a new system and the antispam plugin is the last piece 
I need, everything else is working. Thanks to Johannes for this plugin, 
it's exactly what I want and an elegant solution for filter training. 
But I've been trying everything I can think of for the last 3 days to 
get this to work, no success.

I've got: Postfix 2.5.3, dspam 3.8.0, Dovecot 1.1.6, Maildrop 2.0.4 and 
dovecot-antispam 1.0 tarball.  I've built dspam from source with 
--disable-trusted-user-security to try and isolate the source of the 
plugin problem, which is the message at the IMAP client "Failed to call 
dspam."

Here's what I've got configured for the plugin:

antispam_signature = X-DSPAM-Signature
antispam_trash = trash;Trash;Deleted Items;Deleted Messages
antispam_spam = SPAM;Spam
antispam_dspam_binary = /usr/local/bin/dspam
antispam_dspam_args = --user %u

And here's what happens:
