Sorry about that last E-mail! Here is what I meant:
if (preg_match ("/(@.*@)|(\.\.)|(@\.)|(\.@)|(^\.)/", $emailaddress) ||
preg_match
("/^.+\@(\[?)[a-zA-Z0-9\-\.]+\.([a-zA-Z]{2,3}|[0-9]{1,3})(\]?)$/",$emailaddr
ess))
{
print "That is a valid e-mail.<BR>\n";
}
else
{
print "Not a valid e-mail.<BR>\n";
}
