Subject [jira] [Comment Edited] (VALIDATOR-376) EmailValidator says addresses such as x.y@gmail are valid although most mail apps will fail to send it

--------------------------------------------------------------------

I guess there are two options. When doing a  purely lexicographic validity check of email
addresses the Validator needs a list of valid TLDs and a mechanism to update them. (either
all TLDs or specifically the dotlessones: https://tools.ietf.org/html/rfc7085#section-2.3)

When doing network based validation it needs a way to deal with 127.0.53.53 (and similiar?)
blacklist answers. In case of @gmail. the MX records are caused by  https://icann.org/namecollision

> The VALIDATOR-273 patch causes EmailValidator to allow addresses such as x.y@gmail. Unfortunately,
this is causing us problems as none of the email apps we have tried will actually allow that
email address to be sent. Although the RFCs may state it is valid, in practice it apparently
isn't. Some sort of option is needed to allow providing just the domain to fail. As a consequence
we have had to revert to a prior release of commons-validator.
