The regex is doing exactly what you've told it to do:
[a-z0-9] Match exactly one alpha/number
[-\._a-z0-9]* Match zero or more alpha/number/dot/underscore/hyphen
With the email address rich&[EMAIL PROTECTED] it's basically ignoring
the "rich&" bit and matching on the rest.
Try replacing the regeg with this:
^[a-z0-9][-\._a-z0-9]*@([a-z0-9][-_a-z0-9]*\.)+[a-z]{2,6}$
Note the opening ^ and closing $ : means that it matches exactly that
string -- the ^ is "beginning of string" and the $ is "end of string".
Not only does that make the regex, it also means you can change all
this:
reversedmail = reverse(trim(email));
if (NOT refindnocase("[a-z0-9]", left(reversedmail,1))) {
badmailvar = 1;
} else if (NOT refindnocase("[a-z0-9]", left(email,1))) {
badmailvar = 1;
} else if (listlen(email, "@") GT 2) {
badmailvar = 1;
} else if (NOT refindnocase(regex, email)) {
badmailvar = 1;
}
To just this:
if (NOT refindnocase(regex, email)) {
badmailvar = 1;
}
Because the regex does all the work and you don't need the rest of the
tests.
