This may still not be enough, as what you are trying to do is exactly what some spam tries to do to verify email addresses, and many email programs will, at least by default, block this. Unless you have some "authority" over your recipients so that you can impose a penalty on them for not letting you know that they got the message, it will always be unreliable, and there will always be a significant number of people who have read the message without letting you know of it (unless you put the message in the image, or on a link, so the have to go to the net to see it). -- Richard Damon ------------------------------------------------------ Mailman-Users mailing list Mailman-Users@python.org http://mail.python.org/mailman/listinfo/mailman-users Mailman FAQ: http://wiki.list.org/x/AgA3 Security Policy: http://wiki.list.org/x/QIA9 Searchable Archives: http://www.mail-archive.com/mailman-users%40python.org/ Unsubscribe: http://mail.python.org/mailman/options/mailman-users/archive%40jab.org
