Email/Port Registry Key
The Simple Mail Transfer Protocol (SMTP) is used for email delivery. This
key may be used to specify a port as may be required by your MailHost.
Note that the MailHost and any associated SMTP Authentication settings
(Username and Password) are set by the IPCONFIG command.
By default JANOS will utilize the STARTTLS capability if offered. The
Email/StartTLS Registry key must be enabled.
Port 25 is the standard SMTP port for mail delivery. This port may or may
not require authentication (SMTP_AUTH). It may or may not support STARTTLS
allowing for the encrypted transfer of content. JANOS will use SMTP_AUTH by
default and if STARTTLS is supported will make the secure connection.
Port 587 is the Mail Submission Agent (MSA) port which requires authentication
(SMTP_AUTH). This port may also support STARTTLS. If STARTTLS is supported
(and generally it is) JANOS will establish an encrypted connection and
transfer content securely.
Port 465 is the SMTPS port. This is like the MSA port in that it requires
authentication before mail can be submitted. It also requires that a SSL/TLS
encrypted connection be established initially. The STARTTLS option is not
used. For JANOS to properly transfer mail using this port the Email/SMTPS
Registry key must be enabled.
Note that JANOS can successfully post email using any of the above three
ports. Generally the email content will be transferred securely using an
encrypted connection. That assumes the availability of the STARTTLS option.
But if you need to be absolutely certain of a secure transfer, use port 465
and enable the Email/SMTPS key.
