Port
Port number of the SMTP server used by the system for
sending e-mail alerts.
Email Address in From field
source address from which e-mail alerts are sent
Enforce use of StartTLS (TLSv1)
STARTTLS is an extension to plain text communication
protocols
like SMTP that offers a way to upgrade a plain
text connection to an encrypted (TLS or SSL) connection
instead of using a separate port for encrypted
communication.
Select this check box if you want to
enforce the use of STARTTLS to send e
-mails in an
encrypted format.
Verify SMTP Server's Certificate
Select this check box to verify SMTP server's certificate
against built
-in well-known CA certificates or uploaded CA
certificate. When this check box is selected, an e
-mail is
not sent out if the certificate match fails.
Set Certificate
If an SMTP server's CA certificate is not present in the
built
-in well-known CA certificates packaged in the AirTight
appliance, the test SMTP operation fails. In such cases,
you can upload a private CA certificate of the S
MTP
server. Click this button and then click Choose to add a
private CA certificate file to be used for SMTP server
authentication. If a private certificate is uploaded only this
certificate is used for authentication; the built
-in certificates
will not be
used. If the uploaded file contains multiple
entries only the first entry is used for verification. To delete
a certificate, click Delete for the certificate and confirm
deletion. Note that the server application is restarted after
private certificate upload or delete operation.
Authentication Required
Select this check box to enable SMTP authentication.
Username
user name for SMTP server authentication, when SMTP
server authentication is enabled.
Password

server authentication is enabled.
