the only way i can see this working is that the data which is encoded is in an image and the image has been removed or scrammbled
when sending html emails all images are referenced by absalute paths so when you open the mail the images are downloaded to reconstitute the email look and feel. By generating account details on the fly and saving them as an image so the email calls that data image into the body the auther can do what he likes to the image (deleting it or even scrambling the data inside) given some parameters like obsolete info or change of data

Once an email has been sent, it will be delivered. There is no possibility to "destroy" it or modify it. That's the way SMTP was designed.

yes thats true when using text based email. The email is downloaded and stored on the user machine but when dealing with html email which include images they are called in when the mail is opened as its just <img tags using absolute paths which are pulling them in. The images are stored in tmp until you purge the cache of your browser then when you open that email again the server recalls the images again. If the images are different second time round then your going to see the change in the mail and this may look like the mail has changed on the user machine but its the images that have changed on the server

Good points. Since I never send (and rarely receive) emails with such content, I overlooked that. My impression is that that technique is used mostly by spammers, although somebody can correct me if that's not the case.
