Первый раз настраиваю связку Postfix и Doveсot. Все работает нормально (pop, imap, sasl), до того момента, как я пытаюсь использовать Dovecot как LDA. Т.е. как только я добавляю в конфиг master.cf строчки:

dovecot   unix  -       n       n       -       -       pipe
   flags=DRhu user=virtual:virtual argv=/usr/local/libexec/dovecot/deliver -f ${sender} -d ${recipient}

postfix перестает работать, а в логи спится вот что:

Apr 28 13:57:19 mail postfix/master[978]: daemon started -- version 2.3.14, configuration /usr/local/etc/postfix
Apr 28 13:57:49 mail postfix/smtpd[982]: fatal: no SASL authentication mechanisms
Apr 28 13:57:49 mail postfix/pipe[984]: warning: unexpected end-of-input from dovecot socket while reading input attribute name
Apr 28 13:57:49 mail postfix/pipe[984]: warning: deliver_request_get: error receiving common attributes
Apr 28 13:57:50 mail postfix/master[978]: warning: process /usr/local/libexec/postfix/smtpd pid 982 exit status 1
Apr 28 13:57:50 mail postfix/master[978]: warning: /usr/local/libexec/postfix/smtpd: bad command startup -- throttling

Если убираю все, что связянно с lda из конфигов, то работает.

Привожу полные конфиги Postfix-a и Dovecot-a:
