postfix + spamassassin + dovecot-lda (with sieve support)

Hello,

I have FreeBSD 12 server with postfix + spamassassin. Old config work fine.

------ old postfix master.cf spamfilter unix - n n - - pipe flags=R user=nobody argv=/usr/local/bin/spamc -e /usr/sbin/sendmail -oi -f ${sender} ${recipient}

I try to add dovecot-lda (with sieve support) as local delivery agent to postfix config ----------- postfix master.cf # Spamd filter spamfilter unix - n n - - pipe flags=DRhu user=nobody argv=/usr/local/bin/spamc -e /usr/local/libexec/dovecot/dovecot-lda -f ${sender} -d ${recipient}

The mail system

dol@mig.hys.msu.ru: user unknown

/var/log/maillog Nov 11 22:40:49 mig postfix/smtpd[55978]: disconnect from acs366.hys.msu.ru[93.10.51.14] ehlo=1 mail=1 rcpt=1 data=1 quit=1 commands=5 Nov 11 22:40:49 mig dovecot[64447]: auth-worker(55751): passwd(dol@mig.hys.msu.ru): unknown user

System user dol exist, but LDA try to deliver to dol@mig.hys.msu.ru

Please, help me to solve this problem. I need to serve IMAP and POP3 clients with delivery to /var/mail/username mailboxes if no user sieve rules exists.

Best regards, Dmitry.
