Re: Stopping excessive periods in email

4 things

You'd be better off testing against a blacklist of "rules" (regexes or even better subs) , your approach with or'ed regexes won't be maintainable.
You'll also need a quality management telling you which rule rejected which email address, at least a log
If that's still your formmailer, attackers will quickly learn how to beat your rules.
