Log empty gif module if a connection lasted more than 10s

Server NGINX
1

I’m trying to use the log empty gif module to track wether a recipient
has read
an email (has kept the email open for more than 10s)

I would like to embed the gif in the email html and if the empty gif is
downloaded measure whether the reader has kept the email open for more
than 10
sec. I would like to log that information in the access.log or use
post_action /
proxy to convey the uri with additional parameters to a php script.

I’ve been going through the documentation for a while now but do not
seem to
find how to achieve this.

Any help would be appreciated.

Best Regards

Vladan

I don’t know how your’e going to tell if they kept it open for more than
10 sec. As far as I know there’s no way to do that. Also note that many
email readers purposefully block images in email so that receipt is not
disclosed. I know I use Thunderbird and it does that. I only allow image
display if I know what it is and want to see it. I just wouldn’t depend
on that method.

I know that most email clients block the download of images so I will be
happy
that this works only in the cases where the user downloads the images.
I am thinking along the line of having a keepalive-timout of 10s and if
it
expires to be able to log it.
