Dovecot 1.2.10 in Debian, using Dovecot sieve.

I have a sieve script, generated by Ingo, that's supposed to mark spam messages as "Seen" and file them into the Junk folder. In part it reads:

require ["regex", "body", "imapflags", "fileinto"];

if exists "X-Spam-Flag" { addflag "\\Seen"; fileinto "Junk"; removeflag "\\Seen"; stop; }

This has been working correctly for a long time, but since about 2 weeks ago now, the "Seen" flag isn't being set, although the messages are still being filed into the Junk folder. In two different mail clients, new messages in the Junk folder show up as being unread. Looking at the mail files that hold those messages, the file names don't have an "S" flag appended, while older messages all have the "S" and show up as already seen in the mail clients.

I don't believe that I've updated dovecot recently, so I'm not sure why the behavior has changed. Note that I do have

plugin { sieve_extensions = +imapflags }

in dovecot.conf. I know that imapflags is deprecated, but it is still supposed to be supported. Unfortunately ingo1 doesn't support imap4flags yet (http://bugs.horde.org/ticket/8784).

I'm trying to find log information that might indicate an error, but I'm not finding much. /var/log/exim4/mainlog just says:

2010-02-15 14:22:14 1Nh6WK-000200-8z <xxx@xxx.xxx>: deliver_pipe transport output: deliver(andrex): Info: sieve: msgid=<ad58db2a42700ec0e5c924c8882d48c2@yourmailnews.net>: stored mail into mailbox 'Junk'

The wiki says that there should be a log file ~/.dovecot.sieve.log, but there isn't one, which I guess means there are no error messages.

Output of dovecot -a is below. Any ideas why the Seen flag isn't being set any more?

Thanks, Andrew.
