I created a sieve_default to move any spam-tagged messages into the Junk mailbox automatically, but it doesn’t appear to be working (though the other imapsieve_mailbox… scripts are working).
From doveconf -n
plugin { imapsieve_mailbox1_before = file:/usr/lib/dovecot/sieve/report-spam.sieve imapsieve_mailbox1_causes = COPY imapsieve_mailbox1_name = Junk imapsieve_mailbox2_before = file:/usr/lib/dovecot/sieve/report-ham.sieve imapsieve_mailbox2_causes = COPY imapsieve_mailbox2_from = Junk imapsieve_mailbox2_name = * imapsieve_mailbox3_before = file:/usr/lib/dovecot/sieve/mark-read.sieve imapsieve_mailbox3_causes = COPY imapsieve_mailbox3_name = Archive sieve = file:~/.sieve;active=~/.active_sieve sieve_default = /usr/lib/dovecot/sieve/default.sieve sieve_default_name = spamassassin sieve_global_extensions = +vnd.dovecot.pipe +vnd.dovecot.environment sieve_pipe_bin_dir = /usr/lib/dovecot/sieve sieve_plugins = sieve_imapsieve sieve_extprograms }
And
# cat /usr/lib/dovecot/sieve/default.sieve if header :contains "X-spam-flag" "YES" { fileinto "Junk"; }
There are no user sieve files
# find /home -name "*sieve*" -type f #
The x-spam-flag header in the message in my mailbox is definitely there and definitely set to yes.
