Try this:

Tools Options

"Send" tab.

"News Sending Format" set to "Plain Text"

Click "Plain Text Settings" button

Check mark "Indent the original..." and select '' on the drop down.

I have all of that, and it works well on most people's posts. Some posts
will not respond in the correct manner, with the "" being added, though. I
think it is a problem with how some other people are posting.
