Notifications: TLS Standard vs. Wrapper Mode

[NOYB]

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
