Notifications: TLS Standard vs. Wrapper Mode



  • System: Advanced: Notifications
    SMTP E-Mail

    Having trouble getting notifications to work with Postfix mail server operating in TLS standard mode (non-wrapper mode).  Cannot connect to the host unless mail server is operating in the non-standard "wrapper" mode.

    php: /system_advanced_notifications.php: Could not send the message to pfSense@<domain>.com – Error: could not connect to the host "smtp.<domain>.com": ??

    Standard mode like this for instance fails to connect to the host.  :(
    Postfix master.cf:
    submission inet n      -      n      -      -      smtpd
    **  -o smtpd_tls_security_level=encrypt**
      -o smtpd_sasl_auth_enable=yes
      -o smtpd_client_restrictions=permit_sasl_authenticated,reject

    Non-Standard "Wrapper" mode like this for instance works.  :)
    Postfix master.cf:
    submission    inet  n      -      n      -      -      smtpd
    **  -o smtpd_tls_wrappermode=yes**
      -o smtpd_sasl_auth_enable=yes
      -o smtpd_client_restrictions=permit_sasl_authenticated,reject
