I'm impressed. The php routine passed a@x.com (which is real), but failed a@a.com (which is not real). What's needed is a javascript routine to do the same thing, but it would require a trip to the server to check the domain. As such, I would use AJAX to trigger this php routine to provide validation -- that might prove interesting, huh? Apparent real-time validation -- hmmm, I'm going to think about that. The php routine also passed tedd@xn--nvg.com, which is real -- but it's interesting that most email (if not all) programs cannot show the domain name correctly, which is tedd@*.com. I have yet to find an email program that can show IDNS correctly. Cheers, tedd -- ------- http://sperling.com http://ancientstones.com http://earthstones.com
