Probably You won't need last line, it's used with mail backend only:

Oh my. You've right. I've pasted some config from my test machine, sorry
for this. :) And it was work accidentally, I think :) I'm using:
  antispam_signature = X-DSPAM-Signature
  antispam_spam = SPAM
  antispam_dspam_binary = /usr/local/bin/dspam
  antispam_dspam_args = --user "%u"
So I'm not defining '--source error' option, it's hardcoded. I have
messages with retrain status, so it's ok for me.
And if you apply patch from git sources:
http://git.sipsolutions.net/?p=dovecot-antispam.git;a=commit;h=3da16a1c2e0ed17fc0ca9968ca8b978ce28d51c8
you can add another feature - you can decide what to do if no correct
Dspam signature is found (move silently or produce an error)
antispam_signature_missing = [move|error]

Correct. I realize that is only a workaround, but I don't have too much
time for playing with code.
