I use Thunderbird as an email client, so stayed with version
2.x. (that's TWO, not TWENTY) Later versions added nihil to it's
capacity to receive/send and read mail.
My concern was that IF it now uses the full link to inserted
images in the message body that could be a MAJOR privacy concern.
//"IMPORTANT: The way images are included in a compose window has
changed. Images are now included as data URIs//
As an example, imagine if you were someone sending a photo to
a forum like YouPorn. A posted message with
<file:///C:/documents_and_settings/Boater_Dave/Desktop/Me_and_Clive_having_fun.jpg>
Would be a bit of a giveaway.
Since I don't use the more recent and vulnerable versions,
maybe you could test and send a message with some inserted image to
yourself and then examine the source code of the message received ?
