Hi All

I am using ASP.Net's RegularExpressionValidator to validate email addresses. But this is not working in IEv6 and IEv7.
After research although I found the culprit is lookahead and lookbehind but was unsuccessful in removing them from the regex and get a general regex that runs in all versions of IE.

Regex that I am currently using is:

string pattern = @"^(?!\.)(""([^""\r\\]|\\[""\r\\])*""|"
              + @"([-a-z0-9!#$%&'*+/=?^_`{|}~]|(?<!\.)\.)*)(?<!\.)"
              + @"@[a-z0-9][\w\.-]*[a-z0-9]\.[a-z][a-z\.]*[a-z]$";

Any regex master there who can help me remove lookaheads/lookbehind and get me an equivalent regex or a link that can point me in the right direction.

Thnx
for your time
