Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Hi,

I've developed an eMarketing system that sends email to registered users. Now, is there a way to detect with a Perl script from what email address the message is being opened?

This, without having to manually insert the email address into a query string on a Perl script.

Thanks,
Ralph.
