Hello Machin,
I want to embed and do a page load to send the acknowledgement back to the
sender when the receipt open it.
Is there any better to do it?
Thanks
Most of the mail clients will forbid you doing this, it's just basic
protection. If it would been allowed then a spammer can know if an
email address is valid, it can add a Guid value in the request that
can match with the original email address.
You should do it in another way. You should put a link in the page
that the user should click and then open the real page with all the
flash and other stuff you want.
