Hi Mark, I think I saw something like this over at http://www.regular-expressions.info. I hope I'm right.

Incidentally I appreciate that this will be done on the server-side only, as people can, and do, knock JavaScript off. ----- Original Message ----- From: Katherine Moss<mailto:Katherine.Moss@xxxxxxxxxx> To: programmingblind@xxxxxxxxxxxxx<mailto:programmingblind@xxxxxxxxxxxxx> Sent: Tuesday, May 10, 2011 5:59 PM Subject: RE: Regular expressions to validate Email addresses What is the nature of the program which you are writing?

I'm probably opening up a can of worms here, since I understand that Email addresses are the most argued over when it comes to regular expressions. I'm just wondering if someone could provide me with a few samples, or point me in the right direction where I can find information on this? Currently I'm leaning towards JavaScript, to pass to the match() method of the String object an argument to attempt to validate the syntax of a mail address. Hope this is making sense.
