Hi again.

Aditional info:

1. Incomming emails are delivered correctly
2. I can login / logout into WEB GUI (LDAP should work)
3. Not possible start: systemctl start dirsrv at mail.service (but at another 
functional server I get the same error message)
4. All other services seems to work

Any ideas?

Greetings. ladas
