Use an open-source validator which doesn't give false negatives. Zero effort for you and robust validation for your app.

I've now collated test cases from Cal Henderson, Dave Child, Phil Haack, Doug Lovell and RFC 3696. 158 test addresses in all.

I ran all these tests against all the validators I could find. The comparison is here: http://www.dominicsayers.com/isemail

I'll try to keep this page up-to-date as people enhance their validators. Thanks to Cal, Dave and Phil for their help and co-operation in compiling these tests and constructive criticism of my own validatormy own validator.

People should be aware of the errata against RFC 3696 in particular. Three of the canonical examples are in fact invalid addresses. And the maximum length of an address is 254 or 256 characters, not 320.
