Advanced
• Use SSL/TLS: Select when encryption is used.
– Never: The SMTP server does not require nor support encryption.
– If Supported: The SMTP server advertises support for STARTTLS but doesn't require the
connection to be encrypted. The STARTTLS command is sent after the advertisement is
given.
– Always: The SMTP server requires the STARTTLS command to be sent on connection to it.
– Implicitly: The SMTP server only accepts connections that begin encrypted. No STARTTLS
message is sent to the server.
• Require CA Root Certificate: This should only be enabled if the security policy of your
organization does not allow for implicit trust of SSL/TLS connections. If this is enabled, a valid
root CA certificate must be loaded onto the ATS for encrypted e-mails to be sent.
• File Name: This field is dependent on the root CA certificates installed on the ATS and whether or
not a root CA certificate is required.
Path: Configuration > Notification > E-mail > SSL Certificates
Load a mail SSL/TLS certificate on the ATS for greater security. The file must have an extension of .crt
or .cer. Up to five files can be loaded at any given time.
When installed, the certificate details also display here. An invalid certificate will display “n/a” for all fields
except File Name.
Certificates can be deleted using this screen. Any e-mail recipients using the certificate should be
manually modified to remove reference to this certificate.
Path: Configuration > Notification > E-mail > Test
Send a test message to a configured recipient.
