I think "private/dovecot-lmtp" isn't found. Please compare your Dovecot
socket configuration and Postfix-main.cf configuration to

(The group may not be "postfix" for your system.)

service lmtp {
 unix_listener /var/spool/postfix/private/dovecot-lmtp {
   group = postfix
   mode = 0600
   user = postfix

virtual_transport = lmtp:unix:private/dovecot-lmtp
