Note Submitter: brferreira at grad dot ufsc dot br ---- Paperweight, this pattern worked fine for me (even for intranet adresses, like "john@localhost"; and also for subdomain emails, like "john@foo.bar.com"): '/([a-z0-9])([-a-z0-9._])+([a-z0-9])\@ ([a-z0-9])([-a-z0-9_])+([a-z0-9]) (\.([a-z0-9])([-a-z0-9_-])([a-z0-9])+)*/i' but, still, this won't replace the "activation link", that is the better way to check if an e-mail is valid or not.
