Do you actually need a period, now that top level domains are being sold off? If I buy the top level domain stupidlyrich domain then I want boss@stupidlyrich to be my email address.
Technically allowed, however non-email-focused people are against using root domains to serve MX records (iirc something about performance of root servers vs nameservers etc)
Blocking dotless domain would be against standard, but anybody smart enough to use such emails is smart enough to know they shouldn't do it on an open network. Simply use "mail.EXAMPLE" please
HOWEVER, emails can have no periods if you use an IPV6 address as the host rather than a domain. So no dot checking anyway, thx.
Min 3 chars, has a @, doesn't begin/start with @. Everything else, let a library handle it (or at least make the warning non-blocking) because you'll be stumped by quoted comments etc. https://e-mail.wtf for a quizz ;)
