Why do you want to write buggy code that makes your users hate your program? Don't do it! Write good code, useful code! Validating email addresses is the wrong thing to do. The only way to validate an email address is to ACTUALLY SEND AN EMAIL TO IT. That is all. Just because an address is syntactically valid doesn't mean it is deliverable. You can't validate postal addresses. How would you even try? Even if you could, you wouldn't use a regex for it. That's the post office's job to decide whether mail can be delivered, not yours. Who are you to say that some address in Russia or Bolivia or Kuwait is "invalid"? Email addresses are no different. It is the job of the mail server to decide whether email can be delivered, not yours. http://northernplanets.blogspot.com.au/2007/03/how-not-to-validate-email-addresses.html http://haacked.com/archive/2007/08/21/i-knew-how-to-validate-an-email-address-until-i.aspx http://haacked.com/archive/2007/08/26/dont-be-a-validation-nazi.aspx -- Steven -- http://mail.python.org/mailman/listinfo/python-list
