Email Sending Daemon
The Email Sending Daemon (ESD) assembles an email to be sent to a list or segment of contacts and prospects and delivers each email to the corporate outbound Mail Transfer Agents. Assembly includes adding headers in front of the email message content and merging personalized data into the message content.
The Email Sending Daemon listens on port 8090 for SOAP requests from the Siebel Marketing Server. A SOAP request includes the filename of the email message content, the email message headers, and the Marketing Server subwave contacts and prospects list (containing mail merge data). These files are found in the Marketing File System which is commonly a networked directory accessible to the Email Sending Daemon. The Email Sending Daemon must be able to communicate with one or more outbound Mail Transfer Agents to send mailings over the internet. The Email Sending Daemon must be able to tell the Marketing Server when it has completed a subwave as well as deliver details of email address errors that occurred while it communicated using Simple Mail Transfer Protocol to the Mail Transfer Agents (called synchronous bounces).
The most common placement for the Email Sending Daemon is within the corporate network, behind the DMZ. However, the Email Sending Daemon component can be placed inside the DMZ or outside the firewall, if there is a port opened to connect to the Siebel Marketing Server using SOAP and the networked Marketing File System.
