SUMMARY

How to determine where messages originate using message headers.

DETAIL

Once the message is received by the mail client, you are able to view message headers to get a basic history of each server the message has passed through. The only information that you can rely on though is the most recent Received header added by the MailEnable server and the Return-Path header. These are added to to the email message after it has been received, and the reset of the email may or may not be valid.

If using Microsoft Outlook, you can view message header by double clicking the email to view it in a new window and selecting the File->Properties menu item. In the webmail client you right click the email in the message list and select the option to view message headers.

Example:

Received: from domainname.com ([x.x.x.x]) by domainname.com with MailEnable ESMTP; Thu, 11 Jul 2019 03:29:35 -0400

Reading these "Received" headers from the bottom up will determine the delivery path used. The Return-Path in the email header also indicates the email address used in the SMTP conversation.
