Hi,
I'm developing a software to send newsletter to the users of my
website. I have a problem on the stats, detecting the opening of the
newsletter on the user's client.
The method I've chosen uses an html img tag like this:

<img src="detectscript.php?email=1234"/>

The script "detectscript.php" uses the email-id passed to save the
event "mail open". The script save the "opening" information on the db
and then pick a trasparent image on the server, set the mime type of
the response and send it out to the client.
The script called alone from the browser give the trasparent image
correctly and save the opening event in the db.

So, this method works with some email clients but not with all,
because clients like Windows Mail or Outlook detect that this is a
fake image and they don't call my script. I think that they check the
name of my script... it's a ".php", there are parameters... and they
block it.

Do you have any suggestion to count the newsletter opening correctly?

bye
Giulio
