>>Unfortunately, there isn't really a reliable way to check if a user exists other than sending an email to that address and getting a response.
Right, and I even add and getting a response... from a user who knows that he has a spam folder somewhere and who knows how to look in it. But I'm not looking for a 100% sure test, only for the best possible elimination of bad adresses. I have added my nslookup test called by Ajax in my email validating function and it works well. Before it only checked that the address was syntaxically correct, know, it also checks that there is a mail server at the domain. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:356913 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
