Subject [jira] Commented: (VALIDATOR-292) [PATCH] @localhost and @localhost.localdomain email addresses aren't correctly detected as valid
Date Thu, 17 Mar 2011 12:06:29 GMT

    [ https://issues.apache.org/jira/browse/VALIDATOR-292?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13007896#comment-13007896

Nick Burch commented on VALIDATOR-292:
--------------------------------------

Chatting about this with a couple of other users yesterday, I now think that perhaps this
needs to be an option.

For a dev environment, or maybe for an intranet setup, you might well want to declare @localhost
email addresses to be valid ones. (I certainly do want them to be valid for my use case)

However, for a public, internet facing application, you probably don't want to allow public
users to set an @localhost email address, so for that use case you don't want them to be declared
as valid.

Maybe the solution is to have two methods. isValid(String) would continue to work as before.
isValidLocal(String) would accept @localhost, @localhost.localdomain, and @<machinename>
forms. If you only want valid + public email addresses, you'd then continue to use isValid
as now. If you'd like to also allow local email addresses, you can additionally call the local
one. Any thoughts?
