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

Oh its nothing to important, I'm just wondering about including in a Web form 
some code to try and detect the validity of the syntax of a mail address, or 
not as the case may be.

Incidentally I appreciate that this will be done on the server-side only, as 
people can, and do, knock JavaScript off.

What is the nature of the program which you are writing?

Hello.

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.

Mark
