don't pretend - "postconf -n" and "dovecot -n"
# dovecot
service auth {
unix_listener /var/spool/postfix/private/auth {
mode = 0660
user = postfix
group = postfix
}
}
# postfix
smtpd_sasl_auth_enable = yes
smtpd_sasl_type = dovecot
smtpd_sasl_path = private/auth

* 1025 is not a standard port

because most likely 1025 is not opened in the firewall and even if since
you misconfigured the server it could not connect
