I know about this, but how many domains exists with just a root domain? The vast majority of cases, a missing dot is a typo. I also wouldn't want to imagine how painful using services must be with a foo@bar style address.

The vast majority of common typos result in a syntactically valid email address anyway. A regex is just not an appropriate tool for email validation.

"We can't catch all typos, so we won't catch any" is a silly approach to form validation.

I can't check that 123-45-6789 is a valid Social Security Number, but I can still reject "FARTS".

The same is true for "foo@gmailcom" for a public-internet facing contact us form.

Why not reject invalid top level domains then? This is going to catch a vastly larger amount of typos (including foo@gmailcom) without eliminating any valid emails.
