The basic email address is domain.com but if your in UK it would be domain.co.uk and I saw one the other day sub.domain.name.com. Then there are all the other ones, .bk, .us, .tk ... so unless you had a whole list of all valid domain extensions there isn't really a lot to validate against.</p> <p>So validation is kind of out which leads me to your question. You say you have a sign up, change the sign up so it needs to be confirmed, process like as follows:<br /> members comes to your site<br /> signs up for newsletter or whatever<br /> email gets sent to address for confirmation this is the correct address ...<br /> person confirms info gets stored and used, no confirmation, details dropped</p> Mon, 21 Aug 2006 22:27:55 +0000 Busy comment 1206137 at https://www.webmaster-forums.net
