When I get spam in KMail I'll "bounce" it back to sender. I really like that function, I hope it works.
My question is if I am receiving HTML email instead of plain text and the email gets something from the web to use in its body, will that signal the sender of the spam that the email has in fact been received, making the bounce function useless?
I had just recently switched KMail to use HTML and get what it needed off the web because of a couple of emails I wanted to see in full. I'll prob switch back to plain text now. Is there a way in KMail to tell it by, say, right clicking on a certain email, to use HTML where you know the sender is safe instead of making every email use HTML?

Your help is appreciated.

The major ways spammers determine whether you've viewed their e-mail are:

(a) You click on a URL that has an identifying parameter on it
(b) The mail client displays an external image that has an identifying parameter on it (e.g. img src="http://biz.p0rnwhackers.net/?id=victim347823413" width=1 height=1)

I've been using KMail for a good long while (I *love* the Bounce feature) - and even in HTML mode, I've never seen it pull in external images. The only images it will pull in are inline (i.e. data for them is sent with the message). So, AFAIK, you're pretty safe in KMail in that case. Try sending yourself an HTML e-mail with an externally-linked image (off the top of my head, I have no idea what mail client you can do such a thing in

Mind you, I wish there was an option to, on a per e-mail basis, ask it to show external images. It makes my e-mails from MGM and a few other places I've subscribed to a little difficult to read.
