[Dovecot] antispam plugin: crm114 mode:"antispam signature not found"

[Peter Renner]

Hi there,

I'm happily using dovecot, and today tried to integrate
the antispam imap plugin to automatically train/inform the
crm114 spam classifier when moving messages in and out of
folder "SPAM"

However, when i try to move a message to folder spam,
my client (Thunderbirds) says:

   The current command did not succeed.
   The mail server responden:  antispam signature not found.


Checking the source i found in signature.c

   *signature_hdr = "X-DSPAM-Signature";


This appears to originate from the DSPAM support of the plugin
and apparently doesn't find these header lines.

When using crm114 to sort spam there is no special header
line.  (or i didn't turn it on. do i _have_ to?)


    how can i get that antispam plugin to work with crm114?


I'm using dovecot-1.0.10

TIA
