Re: checking if e-mail address and syntax are valid

Problem with this is that many people use '+' in email addresses along with other strange characters (a friend of mine has an apostrophe in her address at General Electric). Bottom line, trying to catch all valid email addresses using a regex is a really ugly thing to try to do. The one shown here will probably work for 95% or more of them though. As an aside, underscores in domain names are illegal (more correctly, underscores in MX-related DNS records are illegal). As such, you don't need to have underscore to the right of the @ sign in this regex. -d Previously, Nikhil Goyal said: > I wrote a similar script of my own...
