Yes, that's what web bugs are for, but in addition to being annoying invasions of privacy, they are totally unreliable as a means of knowing whether someone read the mail. All they will tell you is that the recipient 'opened' the mail which doesn't mean she read it. Also many MUAs will not load external images in HTML mail without at least asking first so many people may have read the mail without ever loading the encoded image URL. -- Mark Sapiro <m...@msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
