Additional Information
Settings for sending/receiving SMS via SMTP/POP3 protocols
The gateway's internal POP3 server provides SMS downloading from the eCPU via
e-mail. Authorisation goes through the USERNAME and PASSWORD, which are used for
registration to the web-based interface of the eCPU. Every SMS is changed into e-mail
in the
directory after successful authorisation of the CPU. The information Inbox
includes the SMS sender's telephone_number@domain name and the SMS receiver's
telephone_ number@domain name (to set the domain name use the web interface; the
e-mail header and subject of the message are filled in according to the CPU settings).
An already read message can be deleted from the POP3 server. You can delete a
message from the gateway eCPU or mark it as already read, but the POP3 server
cannot see it.
The server awaits e-mail in the format Text/Plain, Text/HTML, Multipart/Mixed or
. From a message in the Text/HTML format, only the body of the Multipart/Alternative
HTML message without formatting is put into the SMS message. From Multipart/Mixed
and Multipart/Alternative messages, only the first part of the message is used,
enclosed between strings and mentioned in the header under the
name. Boundary
The server only supports messages in the 7-bit format encoded according to
ISO-8859-1 or the 16-bit format encoded according to Unicode UTF-8 (messages with
different encoding could be illegible when received in the SMS format).
