[Dovecot] dovecot-antispam: Failed to read mail beginning, Next message unexpectedly lost

Hello,

I'm trying to configure the dovecot-antispam plugin.
Now I've run into a problem: whenever I try to move/copy a message
in/from the spam mailbox, Thunderbird (and also Sylpheed, haven't tried
anything else) says:

The current command did not succeed. The mail server responded: Failed
to read mail beginning.

and in the logs I get:

dovecot: Aug 07 10:41:23 Error: IMAP(username): Next message
unexpectedly lost from 337928
dovecot: Aug 07 10:41:23 Error: IMAP(username): Next message
unexpectedly lost from 337928

The message is not moved/copied.

Dovecot is version 1.1.2, dovecot-antispam is the latest snapshot.
Running on Red Hat Enterprise Linux Server release 5.2, x86_64,
filesystem is ext3 (on lvm).

Attached is the strace -p of the session.

The code seems to be this in i_stream_raw_mbox_read:

           if (stream->istream.v_offset -
               rstream->hdr_offset + new_pos > rstream->mail_size) {
                   /* istream_raw_mbox_set_next_offset() used invalid
                      cached next_offset? */
                   i_error("Next message unexpectedly lost from 
%"PRIuUOFF_T,
                           rstream->hdr_offset + rstream->mail_size);
                   rstream->eof = TRUE;
                   rstream->corrupted = TRUE;
                   return -1;
           }

If I comment it out (after I backup my mail), everything seems to work
as expected.

Oh, sorry, I forgot to Cc the antispam plugin maintainer.

[Dovecot] dovecot-antispam: Failed to read mail beginning, Next message unexpectedly lost

Hi again,

I tried this on Gentoo with dovecot-antispam version 20080601 and
dovecot versions 1.0.15-r1, 1.1.0, 1.1.1 and 1.1.2.
Versions 1.1.0+ all fail.
Version 1.0.15-r1 works fine, even if I add the "Next message
unexpectedly lost" check (see below).

So it seems to be a bug in dovecot (? but I guess it could be
dovecot-antispam, too).

Could someone at least confirm this behaviour?
Note that I use mbox, maildir seems to be OK.
