Hmm, You are right, postfix install inserted into config lines:

# Postfix - suggested configuration taken from SASL_README 
(2.3.2).                                               
    mechanisms = plain 
login                                                                                       

  socket listen 
{                                                                                                  

    client 
{                                                                                                       

      path = 
/var/spool/postfix/private/auth                                                                       

      mode = 
0660                                                                                                  

      user = 
postfix                                                                                               

      group = 
postfix                                                                                              

    
}                                                                                                              

  } 

But right after this comes next, old part:

  # Space separated list of wanted authentication 
mechanisms:                                                     
  #   plain login digest-md5 cram-md5 ntlm rpa apop anonymous gssapi otp 
skey                                     
  #   
gss-spnego                                                                                                   

  # NOTE: See also disable_plaintext_auth 
setting.                                                                
  mechanisms = 
plain                                                                                              


And Dovecot accepts the last one:(.

So it's my mistake, but I was taught, that Dovecot always give error on 
startup, if any double config lines exist.
                                  
Now dovecot -n looks better:

auth default:
  mechanisms: plain login
  cache_size: 1024
  failure_delay: 3
  passdb:
    driver: pam
    args: cache_key=%u%r%s dovecot
  userdb:
    driver: passwd
  socket:
    type: listen
    client:
      path: /var/spool/postfix/private/auth
      mode: 432
      user: postfix
      group: postfix

And also shows up:

50-PIPELINING
250-SIZE
250-ETRN
250-STARTTLS
250-AUTH PLAIN LOGIN
250-AUTH=PLAIN LOGIN
250-ENHANCEDSTATUSCODES
250-8BITMIME
250 DSN

And Entourage works fine. Also with smtpd_tls_auth_only = yes settings.

Super.

Thank You Timo!
