Embedded SMTP Overview

Allegro’s RomMailer product enables your engineering team to leverage the capability to send email from a networked embedded device. With the addition of SMTP and POP functionality, device manufacturers are finding creative approaches to offer specific value “add-on” services, expanding the definitions for maintenance and support, developing novel methods for secure network configuration and provisioning of equipment using standards based email.

RomMailer Basic

The RomMailer Basic is a Simple Mail Transport Protocol (SMTP) client toolkit for sending memory resident text and HTML based Internet email. Messages are sent to any Internet SMTP server which can in turn send messages to any individual or group of Internet email readers.

RomMailer Standard

The RomMailer Standard toolkit adds support to send embedded graphics in an HTML email, send MIME encoded attachments, dynamically insert variables into an email message and send messages from an optional file system or ROM.

RomMailer Advanced

With RomMailer Advanced an embedded device adds Delivery Status Notification, Message Delivery Notification, Message/Partial, Multipart/alternative and SMTP-AUTH support.
