I think you have 2 problems.

first one is with TLS;
the file /etc/ssl/certs/ca-certificates.crt is missing, or can't be read by postfix.
Make sure the file exists and is readable.
My be something went wrong with the installation.
You could try to copy it from another machine.

Second problem is with SASL
Connect to private/auth failed: No such file or directory.
This is the authentication socket that is not created.

This is relative to the postfix working dir.
Mostly /var/spool/postfix/ depends on your postfix configuration.
Try

Code: Select all

ls -l /var/spool/postfix/private/auth

too see if the file exists.

On my system auth this is created by dovecot,
but it can also be done cyrus.

assuming you use dovecot;
Check your config file /etc/dovecot/dovecot.conf
in the section socket listen
it should look like:

Code: Select all

  socket listen {
    master {
      # Master socket provides access to userdb information. It's typically
      # used to give Dovecot's local delivery agent access to userdb so it
      # can find mailbox locations.
      path = /var/run/dovecot/auth-master
      mode = 0600
      # Default user/group is the one who started dovecot-auth (root)
      user = email
      group = email
    }
    client {
      # The client socket is generally safe to export to everyone. Typical use
      # is to export it to your SMTP server so it can do SMTP AUTH lookups
      # using it.
      #path = /var/run/dovecot/auth-client
      path = /var/spool/postfix/private/auth
      mode = 0660
      user = postfix
      group = postfix
    }
  }

As you can see the default client is created as "/var/run/dovecot/auth-client";
I commented it out and created a new path = /var/spool/postfix/private/auth
This one is used by postfix.

Hope this hints help you
