How to Create an EML File

When reporting a False Positive or Negative, occasionally our Support Team will ask for the complete message details in the form of an eml file.

 This file contains the body and envelope/header details needed to verify a misclassification made by the content filtering engine. The eml file allows our analysts to quickly view the actual message and determine if this was a False Positive/Negative message rejection.

The following instructions detail how to find the message in your inbox and generate the required file to remediate a misclassification or False Positive/Negative.

 

Gmail

1. Login to your Gmail inbox and locate the relevant message you wish to use in the eml file. This can be in your "Sent Mail" folder or any place/folder which you have configured in your settings.

2. In the top right corner of your open message and just left of the "Reply" arrow, click on the down arrow or menu box to open a list of tasks available to perform on this message. Select "Show Original" from the list.

3. Once the "Original Message" page loads, click the text link in the bottom left corner to "Download Original".  This will open the file save dialog box on your screen and you should set a name for the file that is indicative of what the file contains(Sender username-domain-date.eml recommended). Change the file type/format from "text" to "all" so that the message is saved with the proper extension you included in the file name, and click on the "Save" button.

4. If you prefer, you can copy the "Original Message" details to your clipboard and paste them into a new file with a similar name and ending in .eml. Google provides a "Copy to Clipboard" button on the "Original Message" screen in the bottom right corner. Copy the message text to clipboard and open any text editor that you have available. Paste the contents of your clipboard copy into a blank document, modify the name and ensure that you use the .eml extension as part of your filename and save the text document.

5. Upload the .eml file as a part of your support ticket or email this file to support@mailchannels.com with a note referencing your original case or ticket number.

 

Outlook

1. Login to your Outlook mail client and navigate to the "Mail View" area. Identify the email message in question and double-click to open it.

2. The message will open in the "Message" window in your Outlook client. On the "Messages" view, locate the "Tags" group and click the anchor at the bottom-left of this area, just left of the word "Tags". This will open the "Message Properties" dialog menu.

3. At the bottom of the "Message Properties" dialog window you will see a section entitled "Internet Headers". Place your cursor into this text box containing the internet headers and select all text (CTRL/CMD + A). With all text selected in the internet headers text box, Copy the headers into your clipboard(CTRL/CMD + C). You can close the "Message Properties" dialog window after copying the internet headers into your clipboard. These headers are the contents of an eml file.

4. Open any available text editor and paste these internet headers directly into the file. Name the file something descriptive (Sender username-domain-date.eml recommended). Ensure that you include the .eml extension on your file name and that you set the File type/format to "all" if it defaults to "text" to preserve the .eml extension and not append .txt to the file.

5. Upload the .eml file as a part of your support ticket or email this file to support@mailchannels.com with a note referencing your original case or ticket number.

 

Mac Mail Application

 1. Login to your Mac Mail client and locate the message "Title" in your client. Click to highlight the message you wish to convert or save as an eml file to highlight/select it.

2. In the "Mail" toolbar, click Mail > File > Save As... This will open the Save As dialog window.

3. In the Save As dialog window you should have the message "Title" which can be left as is or modified if necessary. The Format should default to "Raw", set this if your Format option is not "Raw". Click on "Save" in the bottom-right corner and your file will be saved to the desktop.

 4. Upload the .eml file as a part of your support ticket or email this file to support@mailchannels.com with a note referencing your original case or ticket number.
