> Seriously, what is this thing? It may be an address confirmation scan. If it doesn't bounce it shows that the address is valid. Mailwasher and similar programs foil these by sending back a bounce message. Some also contain a reference to a one pixel picture on a web site. When the email is read that page is accessed. If the page is unique to the message it provides a relatively unseen read confirmation. If you read mail offline and the browser wants to go online at selected messages this can be because they wish to download web content. If there is no visible web content this may be a one pixel probe. A look at the html code will reveal. RM -- http://www.piclist.com hint: The PICList is archived three different ways.
