IIRC when you turn mail debugging on in dovecot the plugin should send the output of the dspam call to the maillog, should tell you what's wrong then...

hello,
i added the dovecot-dspam-plugin [1] to my dovecot-installation. when trying to move a mail out of or into the predefined spamfolder with thunderbird a messagebox shows : "dspam failed" and the message remains in its original position. i am using virtual mail users contained in a postgresql-database [2]. normal imap access and dspam training from the commandline works fine. a posting concerning probably the same issue has been posted on the dspam-mailinglist [3], but there haven't been any helpful replies so far. furthermore i suspect the plugin is missing the --user option when calling dspam, since this seems to be mandatory [4,5], but unfortunately adding this option in the plugin doesn't change its behavior. i am working on a debian system and currently using dovecot 1.0.beta3-3, dspam 3.6.4-2+b1 and the dspam-plugin "for dovecot beta 2 and 3".
- calling dspam from the commandline with the same parameters as in the (slightly modified) plugin works fine

- when dspam is called via the (slightly modified) dovecot-dspam-plugin it aborts (the unmodified version aborts the same way)
