    Please check /etc/postfix/master.cf if you really removed the # in front of the lines that start with 'smtps' and with 'submission' as shown in perfect server guide.

    Hi,
    thanks for your answer.
    i changed the master.cf as follows:
    Code:
    smtp      inet  n       -       y       -       -       smtpd
    #smtp      inet  n       -       y       -       1       postscreen
    #smtpd     pass  -       -       y       -       -       smtpd
    #dnsblog   unix  -       -       y       -       0       dnsblog
    #tlsproxy  unix  -       -       y       -       0       tlsproxy
    #submission inet n       -       y       -       -       smtpd
      -o syslog_name=postfix/submission
      -o smtpd_tls_security_level=encrypt
      -o smtpd_sasl_auth_enable=yes
      -o smtpd_client_restrictions=permit_sasl_authenticated,reject
    #  -o smtpd_tls_auth_only=yes
    #  -o smtpd_reject_unlisted_recipient=no
    #  -o smtpd_client_restrictions=$mua_client_restrictions
    #  -o smtpd_helo_restrictions=$mua_helo_restrictions

    #  -o smtpd_recipient_restrictions=

    #  -o milter_macro_daemon_name=ORIGINATING
    #smtps     inet  n       -       y       -       -       smtpd
      -o syslog_name=postfix/smtps
      -o smtpd_tls_wrappermode=yes

    when i want to send an email in the log this happens:

    Code:

    You missed removing the # in front of the smtps and submission line. Please remove them and restart postfix.
