EmailChecker

Simple library checking the validity of an email. Checks are performed in the following order:

REGEX: validate the emails has a good looking format
MX: validate the domain sever contains MX records
SMTP: validate the SMTP behind the MX records knows this email address (no email sent)

:warning: That's rare but, some SMTP define a catchall email address. Meaning all emails using this domain seems valid even if they are not.

EmailChecker.valid?("kevin@disneur.me")
#=> true
EmailChecker.valid?("non-existing@disneur.me")
#=> false
