Hi That will only tell you they read it, if they have images enabled by default. I don't for instance in my email. If they don't read it with images enabled you can't tell if it was not delivered or just unread.
I wouldn't expect exceptions to be raised from bogus email addresses unless they are malformed, but I would expect a bounce email back to admin email account. Which would be an indication of non-delivery. Rgds Tim -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
