I am not so sure about this regular expression.
I can buy that an email begins with a alpha numeric.
(^[[:alnum:]]
What I don't understand is this part...
([._-]?[[:alnum:]]+)*+
This says (unless ColdFusion regexps are some how really weird) that after the
initial alphanumeric, it is followed by 0 or more cases of 3 puncts,
followed by one or more alpha numerics. This whole string is then required
to be followed by either a plus sign, or an asterisk.
That can't be right... I know _I_ don't have either of those in my email
address.
In most regexp languages, the + has to follow a valid RegExp element. If
the * binds to the paren'd string , then the + would be taken as a literal.
If the * binds tighter to the +, then that says that the * is required to
be present.
\@[[:alnum:]]+([.-]?[[:alnum:]]+)*\.[[:alpha:]]{1,4}$)
Note that there isn't a plus in the host part of your regular expression.
Can you provide an example of the address that is causing the problem?
You wouldn't have to provide the literal address - change the particular
letters in the name and host, but leave the number of letters and the
punctuation the same...
For instance, if the address causing the problem was
[EMAIL PROTECTED]
you could 'encode' it like
[EMAIL PROTECTED]
or some such thing...
