Does anyone know of a way to validate an e-mail address that was entered
and submitted from a form? I would like to trap invalid syntax.
Perhaps there exists a script that does just that?
I assume valid syntax is the following:
One or more characters before the @ sign, followed by an optional '[',
then any number of letters, numbers, dashes or periods (valid domain/IP
characters) ending in a period and then 2 or 3 letters (for domain
suffixes) or 1 to 3 numbers (for IP addresses). An ending bracket is
also allowed as it is valid syntax to have an email address like:
user@[255.255.255.0].
Thanks,
Don
