Usage in Crystal

require "CrystalEmail"

# Pure Rfc5322
# this is what you want if you need to allow local domains
CrystalEmail::Rfc5322.validates? "toto@tata" # => true
CrystalEmail::Rfc5322.match "toto@tata" # => #<MatchData "toto@tata" local:"toto" domain:"tata">
CrystalEmail::Rfc5322.validates? "toto" # => false
CrystalEmail::Rfc5322.match "toto" # => nil

# Rfc5322 + Internet basic usage
# most of the website on internet will require a domain like "domain.thing"
CrystalEmail::Rfc5322::Public.validates? "toto@tata.com" # => true
CrystalEmail::Rfc5322::Public.match "toto@tata.com" # => #<MatchData "toto@tata" local:"toto" domain:"tata.com">

"toto@toto.toto".is_email? # => true
