The configuration options for the SMTP transport are shown below…
•
The Transport Mode property is used to enable or disable the transport. Note that
the mail manager must be enabled via the General tab before the SMTP transport
can be enabled. Note also that either SMTP or SMS must be enabled if the mail
manager is to be able to deliver messages.
•
The Server Selection property is used to define how the transport will locate an
SMTP server. If Manual Selection is used, the Server IP Address property should
be used to manual designate a server. If Configured via DHCP is selected, the
unit’s Ethernet port must be configured to use DHCP, and the network’s DHCP
server must be configured to designate an SMTP server via option 69.
•
The Server IP Address property is used to designate an SMTP server when
manual server selection is enabled. The server must be configured to accept mail
from the Gateway, and to relay messages if required by the application.
•
The Server Port Number property is used to define the TCP port number that
will be used for SMTP sessions. The default value is 25. This value will be
suitable for most applications, and will only need to be adjusted if the SMTP
server has been reconfigured to use another port.
•
The Domain Name property is used to specify the domain name that will be
passed to the SMTP server in the HELO command. The vast majority of SMTP
servers ignore this string. In the unlikely event that your SMTP server attempts
to do a DNS lookup to confirm the identity of its client, you may need to enter
something appropriate to your DNS configuration.
•
The Reverse Path property is used to specify the email address that will be
supplied as the originator of the messages sent by the Fieldbus Gateway. The
property comprises a display name, and an email address. Since the Gateway is
not capable of receiving messages, the email address will often be set to
something that will return an “undeliverable” message if a reply is sent.
•
The Record Log File property can be enabled to keep a log of all SMTP
interactions in the root directory of the CompactFlash card. This file can be
