Dovecot Sieve doesn't move spam to Junk folder in maildir

[Nagy Tibor]

You're right, dovecot was not configured as LDA, I did it, and really I see the 
following line in log/dovecot.info:

2019-08-13 15:49:39 lda(tibor.nagy at softxs.ch): Info: sieve: 
msgid=<5b78f784-9bc4-aa94-219d-25ccb0d11430 at hu.inter.net>: stored mail into 
mailbox 'INBOX'


I've tried also with a test spam mail and I see the following line in 
log/dovecot.info:

2019-08-13 15:52:15 lda(tibor.nagy at softxs.ch): Info: sieve: 
msgid=<904f3c82-6db1-8b5c-d465-ef140c2f5948 at hu.inter.net>: stored mail into 
mailbox 'Junk'


Thanks.

The appropriate configuration lines in postfix/main.cf:


### Configuration for virtual mailboxes
home_mailbox = Maildir/
virtual_mailbox_domains = /etc/postfix/vhosts
virtual_mailbox_base = /home/vmail
virtual_mailbox_maps = hash:/etc/postfix/vmaps
virtual_minimum_uid = 1000
virtual_uid_maps = static:1002
virtual_gid_maps = static:1002

### Configuration for dovecot as LDA (New 2019-08-13)
virtual_transport = dovecot
spamassassin_destination_recipient_limit = 1
dovecot_destination_recipient_limit = 1


The appropriate configuration lines in postfix/master.cf


smtp      inet  n       -       -       -       -       smtpd
   -o content_filter=spamassassin
[...]

### Configuration for dovecot as LDA (New 2019-08-13)
# spamassassin unix -     n       n       -       -       pipe
#  user=spamd argv=/usr/bin/spamc -f -e /usr/sbin/sendmail -oi -f ${sender}

The appropriate configuration lines in dovecot/dovecot.conf:

plugin {
   sieve = /etc/dovecot/sieve/default.sieve
}
protocol lda {
   mail_plugins = $mail_plugins sieve
}
