If you are sending email through some kind of script (whether it be perl, asp, cold fusion, whatever) you have to specify the from address as well as the to address. What most of these places probably do is loop through the email addresses (sending an email at each loop iteration), and output the email address as both the "to" and "from" addresses. . hope that makes sense. Or if the "to" and "from" addresses are those of the sender, they must have used the "bcc" field to direct email to all their users. You can do this too in any email client.
