Subject RE: [validator] EmailValidator 1.4.1 returns true for some invalid(?) email addresses
Date Tue, 16 Jun 2015 17:19:00 GMT
Hi Ayoma,

RFC 5321 goes on to say, "This makes the requirement, described in more detail below, that
only fully-qualified domain names appear in SMTP transactions on the public Internet, particularly
important where top-level domains are involved."

Does EmailValidator provide a way to validate an email address is valid for use on the public

Hi Dave,

Mentioned email addresses are valid and they are mailboxes for TLD users ("gmail" is a valid

Please check following :

Bug report :
RFC:   * (states : In the
case of a top-level domain used by itself in an email address, a single string is used without
any dots.)*

Best Regards,
