Eudora for the PC – there are 2 slightly different methods depending on whether the mail contains HTML or not.
In any case, to prepare for HTML email, you should turn off the use of Microsoft’s HTML viewer. To do so, click Tools, then Options, then Viewing Mail. Uncheck the box labeled “Use Microsoft’s viewer.”
How to know if it’s HTML mail: once you have opened the email, look near the bottom of the headers (see below for revealing headers) for a line like the following: Content-Type: text/html … you can frequently spot HTML email because it has font effects, pictures, etc but this is not always true so you have to take a quick look at the headers.
Eudora for the PC – non-HTML mail:
- Open the email by double clicking on the subject line. Click the button to reveal the headers.
- Place your cursor anywhere in the body of the email and select the entire message (Edit/Select All or Ctrl-A)
- Copy the entire email (right click and click copy OR Ctrl/C OR Edit/Copy)
- Paste (right click/paste or Ctrl/V).
Eudora for the PC – HTML mail:
- Open the email and click the button to reveal the headers.
- Highlight the headers only. Copy and paste the headers.
- Hit enter twice after the pasted headers to force a blank line after the headers.
- Back in Eudora window, place your cursor anywhere in the body of the message and right click and click “view source”. A new window will open.
- In the new window, select all (as above) and copy the contents of the new window.
If the feature is enabled, you simply press H to toggle full headers. If the feature is not enabled, you must enable it first: From the main menu, press (S)etup, (C)onfig. Scroll down about 40 lines to the option labeled “enable-full-header-cmd.” Press [ENTER]. Press (E)xit, (Y)es – to save. Then you can return to the message window and use H to display the headers.
To get mutt (the mail user agent) to forward the full headers (not display them for viewing), use the command “unset forward decode” in your rc file or directly in the command interface.
Open the email, click on “Actions” then on “Delivery Information.”
Next, you have to pick out the internet-style mail header information from the window that appears when you select Delivery Information.

Look for the first line that begins with “Received”. There should be a blank line just above it. Then, scroll down to the next blank line. The stuff in-between the two blank lines are the headers you need.

Look for the separator line that reads
——– Additional Header ——
Select everything from there down to the next separator line, usually
