There's often value in even only partially-effective checks though. With an email address you can easily check to see if it has an "@", and if the stuff after the "@" is a syntactically valid domain name. You can also go a bit further and check to see if the domain has an MX record, and if it doesn't then it is extremely unlikely that the address is valid. -- https://mail.python.org/mailman/listinfo/python-list
