Hi!

I have the same problem right now. I tripple checked all the config
files. First, I was using dovecot 1.1.1 (which could not work, as I read
in the archives), then tried it with 1.1.3 and now with version 1.1.2.
I have a virtual mail setup with postfix, mysql, dspam, amavis-new,
clamav and spamassassin.

The problem seems that the antispam plugin cannot run the dspam binary,
although its path is properly specified (in my case on DragonFlyBSD in
/usr/pkg/bin/dspam). With debug to syslog all variables are shown in as
they should.

The plugin also reacts when I try to move the spam-mail to the Spam
folder. (I redefined the SPAM-folder to be called Spam)

If I reassamble the command on the shell (I need to add --user
dl at pless... to the command with the signature) , dspam retrains the
message in its database.

So it seems that dovecot seemed not to be able to run dspam. I enabled a
shell (temporarly) for dovecot and run dspam from there, and it
succeeded. It just doesn't work from the plugin.

What could I check next? I really like the idea behind the plugin and
would like have it working.

I am using the antispam git-version from 7. Sept. 2008.

Thanks in advance
