Hi Marc,
[+list since I'm unlikely to be able to solve this problem myself]
I am trying to setup a debian testing (wheeze) mail server using
postfix, dovecot and amavisd-new with spamassassin. I have everything
working fine, using mdbox mailboxes and system users. As a final touch
for this setup, I wanted to be able to train the (global) bayes
database directly through IMAP.
Hence, I installed your plugin (directly from the official debian
repositories) and set it up to report mails to spamassassin. I am
using the pipe backend to call a wrapper script, that stores the
mail into a temporary file and launches sa-learn to learn it. My tests
indicate that this is working properly.
Ok, nice.
However, when the dovecot-antispam plugin is enabled, I have a weird
problem sending emails. This is, whenever my MUA tries to save the
just sent message to the Sent folder, dovecot shows the following
error:
Hmm, ok, let's see

Dovecot's error log:

As a result, the MUA hangs for a while (some minute and a half). After
that it closes the IMAP session properly, but I am left with two
copies of the sent email in the Sent folder: one that is marked as
unread and one that is not.
Curious. I think the problem is likely the mdbox storage... There have
always been some issues with it and the antispam plugin when combined.
The first issue was that we couldn't access the raw text or
something ... not sure what's up now.

That looks ... pretty normal.
At this point, I do not know what else to try or how to fix this
problem. Thus, I have had to disable your plugin for now. Do you have
any ideas on how to proceed? I can give you access to this machine if
need be (it's a personal server).
Unfortunately, I don't. I can only suggest, as a test, trying with some
other storage format -- I only use Maildir -- to see if the problem is
really in the interaction with mdbox. I'm fairly sure that's likely the
problem, maybe the plugin doesn't pass something through append that is
needed by mdbox, but I've never even attempted to understand mdbox.
Maybe Timo can comment. Timo, you can find the latest code here:
