In your slides "Sending E-mail that reaches the destination using PHP", you wrote:

a) To know when a message was received, you advise to insert a beacon image in an HTML message and you propose an example with parameters.

b) To avoid confusion with spam, you advise not to send messages with beacon image URL that has parameters.

So what?

The difference is using URL parameters.

For instance a beacon image URL like this will be detected by SpamAssassin as a beacon:

mysite.com/read.php?user=some_user_ ...

But this may pass:

mysite.com/read/user/some_user_id.g ...
