In the N4 Settings view (on page 1) (Administration 
Settings Settings), set the following settings:
N4 supports authenticated SMTP over Secure Sockets Layer (SSL) / Transport Layer Security (TLS) . Authenticated SMTP over SSL/TLS enables a user to communicate over an encrypted channel after verifying an SSL/TLS certificate.
To configure N4 to communicate with an SSL/TLS-enabled email server:
In the N4 Settings view (on page 1) (Administration Settings Settings), set the following settings:
MSEMAIL_SERVER_CONFIG001 (HOST) - Host name the remote email server. For example, smtp.gmail.com.
MSEMAIL_SERVER_CONFIG002 (PORT) - SSL port of the email server. For example, 587 for gmail with smpts protocol.
MSEMAIL_SERVER_CONFIG003 (PROTOCOL) - Must override with 'smtps' to indicate that it is SSL-enabled.
MSEMAIL_SERVER_CONFIG005 (SMTPS_USER) - User name for accessing the remote SSL-enabled email server.
MSEMAIL_SERVER_CONFIG006 (SMTPS_PASSWORD) - Password of the user name defined in MSEMAIL_SERVER_CONFIG005 (SMTPS_USER).
MSEMAIL_SERVER_CONFIG008 (ENABLE_STARTTLS) - Set to 'True' to enable the use of the STARTTLS command (if supported by the server) to switch the connection to a TLS-protected connection.
When the value for this setting is 'True', MSEMAIL_SERVER_CONFIG003 (PROTOCOL) must be set to 'smtp'.
To test, create a general notice (on page 1) that sends an email and trigger an N4 event to see that the email is delivered.
