General operation of the e-mail system
The recorder sends messages for distribution by an e-mail server. The e-mail server is
located by its IP address or it's name as set-up in the communications set-up options.
When the recorder sends an e-mail message, it locates the e-mail server and uses
SMTP (Simple Message Transfer Protocol) to send the message to the e-mail server.
SMTP allows the recorder to send messages to an e-mail server without having its own
e-mail address; because of this the e-mail server will not be able to send any reply back
to the recorder.
When setting-up the e-mail address list, it is important to include the e-mail administrator
address. The Administrator e-mail address is the e-mail address to where the e-mail
server will respond in the event of any problems with the delivery of e-mail messages.
The Administrator will also appear to be the source of any e-mail messages sent by the
recorder. Most e-mail systems require a 'Reply To' address as part of an e-mail message,
since the recorder does not have its own e-mail address; it uses the e-mail administrator
as the 'Reply To' address.
Any e-mail message will consist of a delivery list (recipients), a subject, and an optional
message body. The message body may be omitted for very short messages, or where
the message is to be sent to a paging system.
The e-mail subject may be either one of the existing event markers, or one of the two e-
mail subjects. The e-mail message body may be either one of the existing event markers,
or one of the two e-mail message blocks. Event markers are restricted to 80 characters
each. The two e-mail message blocks are restricted to just over 1000 characters each.
Both the message subject and body may contain embedded marker tags as used in the
event markers.
When the recorder sends an e-mail message that includes a message body, the recorder
name, recorder number and the time/date will be appended to the end of the message
body text. This is to allow easy identification of when the message was send, and by
which recorder.
Any e-mail message is sent as an action within the recorder events system, so anything
that can be configured to act as an event cause, may be configured to send an e-mail
message. Any e-mail message may be sent to up-to 12 of the recipients. If the e-mail
server supports named groups of e-mail addresses, an e-mail message may be sent to a
combination of e-mail addresses and e-mail group.
