You guys aren't validating an email-address. You just send something to an address some gives. If the mail doesn't arrive.... bad luck for that guy. That's no way of validating an address. That's just sending an email to whatever address someone gives. Realy validating the address is checking whether or not it exists _WITHOUT_ sending an email. Sometimes you just have to live with those things that aren't possible.... like quickly and savely validating an email-address. Like Steve and I already posted; you can check the domain and that's it. Everything that goes beyond that is just trail-and-error checking. That's not the way. E.g. if you have some site and you want to collect marketing information you want the email-addresses to be correct. But _noone_ will ever fill out some form -> check his mail -> come back to a given URL -> and validate some password. That's only a possibility for sites where people can create an account of some sort. When it just concerns some visitor information, there is no reliable way of checking the complete address. Just like e.g. the first- and lastname of the visitor. You just _cannot_ check that! -- * R&zE: *************************** ** Renze Munnik ** ** E: renze@datalink.nl ** M: +31 6 218 111 43 ***************************
